Image Processing Toolbox™ Hyperspectral Imaging Library provides MATLAB® functions and tools for hyperspectral image processing and visualization.Use the functions in this library to read, write, and process hyperspectral data captured by using the hyperspectral imaging sensors in a variety of file formats. The library supports national imagery transmission format (NITF), environment for visualizing images (ENVI), tagged image file format (TIFF), and metadata text extension (MTL) file formats.The library presents a set of algorithms for endmember extraction, abundance map estimation, dimensionality reduction, band selection, spectral matching, and anomaly detection.The Hyperspectral Viewer app enables you to read hyperspectral data, visualize individual band images and their histograms, create a spectrum plot for a pixel or region in a hyperspectral data cube, generate color or false-color representations of hyperspectral images, and display metadata.For more information on Hyperspectral Imaging Library see the documentation - https://www.mathworks.com/help/images/hyperspectral-image-processing.html
It allows user to do transfer learning of pre-trained neural network, imported ONNX classification model or imported MAT file classification model in GUI without coding. Other than using the existing model, user can design their neural network using Deep Network Designer (MATLAB built-in application) and later use this app to train the neural network. User can analyze the pre-trained network or imported network in this app. It also allows user to modify the image augmenter information and training option (hyperparameters). Once completed the training of network, user may export the trained network to workspace, MAT file, ONNX file and generate MATLAB code for the steps being done in the application. User can generate NVIDIA GPU CUDA Code, however it is not supporting imported ONNX model.Pre-trained Neural Network available :1) alexnet2) googlenet(ImageNet)3) goolgenet(Places365)4) resnet185) resnet506) resnet1017) vgg168) vgg199) inceptionv310) inceptionresnetv211) squeezenet12) densenet20113) mobilenetv214) shufflenet16) xception17) nasnetmobile18) nasnetlarge19) import ONNX model20) import mat file model[Up to R2019a, imported ONNX layer is not supporting generation of CUDA code]How to design & train neural network using this app?https://www.youtube.com/watch?v=-GeZa6IL2QAHow to import ONNX Model to train using this app?https://www.youtube.com/watch?v=8pZiduqp35g

This contains Matlab code to load the content of an SVG file into a simple Matlab structure (loadSVG.m), to save a Matlab structure containing polygons and images into a SVG file (saveSVG.m) and a function to display this structure in a Matlab figure (plotSVG.m). It is possible to edit the polygons interactively within a matlab figure using plotSVG with true as the second argument. This code handles polygons but not bezier curves yet.
Structures are a convenient way of carrying around many variables as a single object and of passing those variables to a function packed in a single argument.Once a structure has been passed to a function, however, many users (according to various Newsgroup posts) find it tiresome to have to access its fields repeatedly through dot-indexing notation and have sought automated ways to take a structure and assign all of its fields to separate variables, as ina = myStruct.a; b = myStruct.b; c = myStruct.c; etc...Solutions based on assignin() have often been tried, but are hazardous, for reasons discussed, for example, in this thread:http://www.mathworks.com/matlabcentral/newsreader/view_thread/244639#628695The structvars() tool in this FEX submission does something virtually as good and far safer. Given a structure, it will print the lines of code needed to assign structure fields to separate variables (or the reverse). The lines of code can be conveniently copy/pasted from the command window to the file editor at the location in the file where the variables need to be unpacked. Examples: Given structure myStruct, with fields a,b,c, & d (1) structvars(myStruct) %assign fields to variables ans = a = myStruct.a; b = myStruct.b; c = myStruct.c; d = myStruct.d; (2) structvars(3,myStruct) %split the last result across 3 columns ans = a = myStruct.a; c = myStruct.c; d = myStruct.d; b = myStruct.b; (3) structvars(3,myStruct,0) %assign variables to fields ans = myStruct.a = a; myStruct.c = c; myStruct.d = d; myStruct.b = b; The commands can obviously be regenerated if you add/remove structure fields later on. On the other hand, the effort of just making these incremental edits manually is typically minimal.
We present the ‘SDF Importer’, a package developed to enable reading of HP/Agilent/Keysight Standard Data Format (SDF) files (v3.0 and below) within MATLAB and Octave.We provide a brief introduction to the package’s functions, a description of the structure of the extracted data, and step by step instruction on extracting and displaying single-trace and multi-trace datasets. Additionally an assessment of the importer against the Standard Data Format Utilities supplied with original HP equipment is performed.Note: See updates notes in SDF_import.m regarding engineering units bug.

Some elements of BerkeleyMadonna are not supported, however:(i) difference equations(ii) higher-order equations(iii) ODEs in STELLA notation(iv) if/then constructs and logical operators among othersPlease check the code to see a complete listing of unsupported elements. Step functions in the BerkeleyMadonna model are converted into equivalent SimBiology constructs (doses or events).
This version is currently ASCII only but future revisions will support binary. This function is based off of Luigi Giaccari's STL importer but uses the textscan function to dramatically increase speed, which makes a significant difference for large files.
LTSPICE2MATLAB imports an LTspice IV .RAW waveform file containing data from a Transient Analysis (.tran) or AC Analysis (.ac) simulation, and converts voltages and currents vs. time (or frequency) into a Matlab data structure. This function can read compressed binary, uncompressed binary, and ASCII file formats. In the case of compressed binary, the data is automatically uncompressed using fast quadratic point insertion. This function handles very large binary simulation files efficiently, and has an option to load only a subset of a file's waveforms to reduce memory consumption. Type >> help LTspice2Matlab for details.Use LTSPICE2MATLAB to import LTspice waveforms for additional analysis in Matlab, or for comparison with measured data. LTspice2Matlab has been tested with LTspice IV version 4.01p, and Matlab versions 6.1 and 7.5., and regression testing has been used to expose the function to a wide range of LTspice settings.Note: LTspice IV is a Spice III simulator and schematic capture tool freely avaliable for download at www.linear.com/designtools/software. It is optimized for simulation of switching regulators, but can simulate many other types of circuits as well and comes with a variety of component models.
Reads data from a fixed width textfile (i.e. the numbers are arranged in columns that are a given number of characters wide). Non-numerical data is converted in NaN. You can use this function for reading very large files in chunks, because you have to specify the line where to start reading (first line = 1), and the number of lines you wish to read.Input: - filename (string): filename to open (you have to include the extension) - startline (int): line where to start reading - number_of_lines (int): number of lines you want to read - columns_width (vector): A vector containing for each column it's width. (The width of a column is the number of characters it is wide.) Output: a matrix containing the read data.01/05/2006, Adriaan Van Nuffel

This M-File imports data from binary *.dat files, created with PSpice. It has been tested for PSpice 6.0 (DOS), 9.1 (Student), 10.0.3 and 16.2.0. If you are using other versions of PSpice, you might need to adjust the code!The M-file further has been tested with PSpice's transient analysis, AC and frequency sweeps. However, it might not be able to import digital data. I would be happy to help out, if you can provide a small sample file created with another version of PSpice or containing a different data type
FAMOSconnect(filename)reads a (MARC generated) FAMOS file. It returns a struct that contains information about the stored signals and memory-map links to the actual data. No actual data is loaded yet. Thus there is no memory based limitation to length of source file.FAMOSload(map,signal)loads specific signals from a map struct provided by FAMOSconnect.FAMOSimport(filename)opens (MARC generated) FAMOS files and imports all signals.
As txt2mat basically is a wrapper for sscanf, it quickly converts ascii files containing m-by-n numeric data, allowing for header lines. When encountering rows with different numbers of data elements, it will work line-by-line and thus slow down somewhat.You may let txtmat carry out an automatic data layout analysis on comparatively 'simple' text files (header lines + decimal number data with common delimiters). By this analysis it is able to directly import most numeric .csv-files, for instance.As txt2mat can perform string and regular expression replacements before the numeric conversion, it can cope with many irregularities within the data. By that it is also capable of detecting and handling commas as decimal characters (common german notation).You can filter lines by keywords, skip lines by line number, provide appropriate format strings (as for sscanf), or split up the import process for huge files if you encounter memory problems.You may also use the above to simply read the manipulated text into a character vector or to put each line into a separate cell or string vector element without the numeric conversion.txt2mat should work on Matlab R2016b and newer versions.Comments and suggestions welcome.Andres
This code is an updated version of MATLABIO which supports import/export of .MAT files under Mathematica v5.2 and Matlab R2006a.Using the example Mathematica notebook supplied, it is trivial to exchange numeric matrices between Matlab and Mathematica.Updated by:Chris Rodgershttp://rodgers.org.uk/
The m-file reads a SPICE3 text output file and imports the data into MATLAB. Whether it works or not really depends on your version of SPICE and what kind of circuit simulation you are doing, but if this m-file doesn't work for you, at least it should be a good starting point. See the help comments in the m-file for more info.
The function provides a simple method with which one can load the contents of open document spreadsheets into MATLAB. Allowing users to directly import files created by Open Office into MATLAB.Provided with the filename of the spreadsheet the function will import the contents into a MATLAB cell array. The function handles the presence of multiple worksheets by allowing the user to specify a particular worksheet to import.The function has not undergone rigorous testing, but it has worked for all of my needs. Also, I think a similar method may be implemented to allow one to export data from MATLAB into open document spreadsheets.Based on Alex Marten methods.
This function parses a Modelica result file (*.mat) into a tree structue so that all variables can be accessed the same way as in Modelica.The path to the result file has to be provided. The user can also pass a regular expression to the function to limit the return variables.The output is a nested structure where all variables can be accessed via dot-notation. Arrays of objects in Modelica are parsed into arrays in Matlab. res = modelicaImport(path, regex);eg. res.object.subObject.variableeg. res.object.subobject(1).variableThis function is pretty much a byproduct of a simulation project I did for university - I hope that is is useful. I have used this function with OpenModelica 1.9.1+dev (r22052) and Dymola 2015.

PyColormap4MatlabSimple Matlab and python script that import colormaps from matplotlib into Matlab.getPyPlot_cMap returns any colormap implemented in the matplotlib python library. It calls a python script that writes the colormap matrix into a temporary file, i.e. python (and the matplotlib module) is required.However, the advantage is that you get all the colormaps implemented in matplotlib and that you can specify the number of RGB quantization levels, i.e. the number of colors of the colormap.A list of colormap names is provided in the function help section. getPyPlot_cMap('!GetNames') returns a cellstring containing all available colormap names.See https://matplotlib.org/examples/color/colormaps_reference.html for an illustration of colormaps.Also available onUsagecMapNames = getPyPlot_cMap('!GetNames')Returns a cellstring containing all available colormap names.cMap = getPyPlot_cMap(cMapName)Returns the colormap cMapName with the default of 128 colors. cMap will be a 128x3 matrix.cMap = getPyPlot_cMap(cMapName, NumberOfColors)Specify the number of colors, i.e. the number of rows in cMap.cMap = getPyPlot_cMap(cMapName, NumberOfColors, keepAlphaChannel)If keepAlphaChannel is not 0 cMap has a 4th column containing the alpha channel.cMap = getPyPlot_cMap(cMapName, NumberOfColors, keepAlphaChannel, pythonSystemCommand)Lets you specify the python command (possibly including a path, see below) used to execute the python script.ErrorsIf you have python installed but Matlab says There was an error executing the command...

Two functions for the import of TwinCAT Scope View data into MATLAB and for reformating the data in order to be able to perform mathematical operations between different measurement channels, if necessary.See included documentation for details.
This function reads the mesh data for all structural elements listed below, but includes corner nodes only (i.e. disregards any midside nodes). Both displacement- and stress results are imported. All data is returned in the "model" struct as explained below. The function is intended for further postprocessing FE results in Matlab.Before using the function, the ANSYS model must be exported to a text file. Use the supplied "export.mac" to do this. In Workbench, add a "Commands (APDL)" block under "Solution" and paste in the macro contents. In Classic, run macro by clicking "File>Read input from..." and selecting the "export.mac" file. This will create the file "model.txt" located in the ANSYS working folder: C:\...\ANSYS_WORK_DIR\JOBNAME_files\dp0\SYS\MECH\model.txt where "ANSYS_WORK_DIR" and "JOBNAME" are names chosen by yourself.Supported element types: - SOLID187 (3D tetrahedral solid) - SOLID186 (3D hexahedral solid) - PLANE42, PLANE82, PLANE182, PLANE183 (2D 4/8-node quad/triangle) - SHELL181, SHELL281, SHELL63 (3D 4/8-node shell)INPUTS: path\filename of the ANSYS export file "model.txt" (string).OUTPUTS:model.filename = path + filename of the model filemodel.raw = raw tables from ANSYS.etlist = element type list: [type_no, ansys_name, internal_type].nlist = node list: [node_no, x, y, z].elist = element list: [elem_no, type_no, mat_no, node1, ..., node8, com_x, com_y, com_z].flist = face list: [node1, node2, node3, node4, elem_no, centr_x, centr_y, centr_z].stress = stress results: [node_no, Sx, Sy, Sz, Sxy, Syz, Sxz].disp = displacement results: [node_no, Ux, Uy, Uz, Usum]model.surf = same as above, but containing surface nodes/elements only.nlist = same as above, but containing surface nodes/elements only.elist = same as above, but containing surface nodes/elements only.flist = same as above, but containing surface nodes/elements only.stress = same as above, but containing surface nodes/elements only.disp = same as above, but containing surface nodes/elements onlymodel.surf.mapping = maps between names and indices for nodes, elements and faces.node2ni = node_no (externally referenced number) -> node index in nlist.elem2ei = elem_no -> element index in elist.face2elem = face index -> element name.ni2face = node index -> face index.ni2ei = node index -> element indexThere are two sub-structs in output model: "raw" and "surf". The first contains the raw reading of data from the ANSYS export (ETLIST, NLIST, ELIST, PRNSOL,S and PRNSOL,U). The second contains the same, but for a reduced surface model, which is "scooped-out" such that only the surface nodes/faces of the elements are included. This is expedient to reduce the computational load of plotting solid models (i.e. not plotting the internal nodes/elements)EXAMPLES:1) Planar model: mesh with node numbers and stress contours with deformed shape.2) Solid model: showing a reduced (surface only) model.3) Shell model: showing a 3D shell structure in deformed configuration.
After import the function creates two struct variables that contain all the data in a nicely ordered way. For every column in the log file a field entry with the same name is created.The output variables are either a vector of structs (one entry per line in the log file) or a struct that contains vectors in each field. This makes it easy and hopefully flexible enough for everyone to start the analysis using MATLAB.

This function imports Arc-Info ASCII Raster (e.g. *.asc, *.txt) files. You are allowed to import single or multiple files by multi-selection (CRTL + Mouse_Left_Click). In the latter case by default a structure array is created in order to store the several rasters; items of the structure array are called as the imported raster. A facultative option is now added to create a stack of double 3-D array instead of a structure array in case more grid files are selected. This might be useful to handle for instance multi-temporal remote sensing datasets (such as NDVI), or multiple realizations of Geostatistical Simulation. The dimension of the stack you can create depends on your computer hardware.
There is no tool around to import WinWCP (John Dempster, University of Strathclyde, UK) files into MATLAB, as far as I know. import_wcp is a simple importer for .wcp patch clamp recordings into Matlab. The recordings can be also plotted with the function plot_wcp. See help code inside the functions for parameters & feel free to extend the functions...
The file may not be time and space efficient but i think its well documented and can be easily understood by beginners.To avoid complexity file does not consider normal vectors.
Import or convert a LabView TDMS file (version 1.0 through 2.0). Interleaved and Non-Interleaved tdms files are supported.These functions also work with tdms files that contain channels using the DAQmxRaw data typr (raw ADC data written by LV), if the files are translated first using the information found at: https://decibel.ni.com/content/docs/DOC-32817Adding another submission so that Robert Seltzer who has provided a great deal of support for several years and is no longer actively working with TDMS files can hand back off development.It was written in MATLAB 2010b. The original function was based on the work by Brad Humphreys of ZIN Technologies and Grant Lohsen & Jeff Sitterle of GTRI (versions 1 through 4 of this function). The Version 9 function (written by Philip Top), in addition to incorporating the various updates that were added to previous versions, can process files that have been "optimized" by LabView. Robert Seltzer of Borg Warner has provided a great deal of support and input. this version is the first using FileEx's new GitHub interface (thanks Mathworks!).This function has been tested with a limited number of diverse TDMS files.
This script acts to import files from Gatan's .DM3 file format, utilized for electron microscopy, into a MATLAB structure. The fields of the MATLAB structure can then be referenced with the dot-operator.For example, one can load and display a file with the appropriate scaled axes in nanometers and electrons with the following example script: dm3struct = DM3Import( 'RandomBrightfieldImage.dm3' ); N = length( dm3struct.image_data ); imagesc( (1:N).*dmstruct.xaxis.scale (1:N).*dmstruct.yaxis.scale, ... dm3struct.image_data.*dm3struct.intensity.scale );This script currently imports images, EELS spectra, and spectral images. Now imports annotations (text) written on the image as well.This script was constructed largely by parsing example DM3 files with a hex editor. It uses regular expressions to find the tags that indicate the start points of the various fields within the files, and then strips the data. To the best of my knowledge there is not existing documentation on the actual object used to write DM3 format files so it is not practical to output to DM3 format.
Both numeric and text is imported. For the non-numeric cells, the numeric values are NANs.There are several options, depending on the input and output arguments. If no output arguments are requested, the data is displayed to the screen. It is a good idea to verify the import by using the no-output option. It is possible to import selected columns by specifying the header string. If no header strings are supplied, then the entire spreadsheet is imported.
xmlData.m extracts data stored in an xml file and returns variable(s) to MATLAB. There is also an optional argument to accept an xml transform to convert the xml file into the required form.The purpose of this function is to allow data-driven MATLAB programming while maintaining a data file that is used by other applications and is also human readable.

This function imports .HGT "height" binary data files from NASA SRTM global digital elevation model of Earth land, corresponding to 1x1 degree tiles of 3-arc seconds resolution (SRTM3, around 90 m) and 1-arc second (SRTM1, around 30 m), and returns coordinates vectors latitude and longitude, and a matrix of elevation values.The function includes also an automatic download of data from the USGS SRTM webserver, so indicating latitude and longitude is sufficient to get the data and instant map plot anywhere in the World. Few examples: readhgt(46:47,-123:-122)plots a map of Seattle and surrounding volcanoes, X = readhgt(48,2,'plot');plots a map of Paris (France) and returns downloaded SRTM data in structure X.Type "doc readhgt" for syntax, options, other examples and use.
The Thorlabs PM100D is a laser power meter console that can record data directly to a memory (SD) card. The data are measurements of the laser power incident on a sensor over a time period. This MATLAB function imports the data files saved to the memory card.More information about the PM100D power meter, including the manual, is available from Thorlabs:http://www.thorlabs.de/thorproduct.cfm?partnumber=pm100d
MatLab function to import a file in the CEF 2.0 format (ITU Recommendation ITU-R SM.1809). This format was created to exchange radio monitoring data between members of the ITU (International Telecommunications Union).The function loads and decodes the CEF-file to variables in the MatLab workspace. MultiScan files are supported.The workspace is also saved in a MAT-file with the same name. Second loading is very fast as it will use the MAT-file.
After execution of the M-File catman_read, the content of binary catman DAQ files are available in MATLAB. Two structured variables (one with global content, one with DAQ data) are delivered by the M-File.Catman Online Data files are not supported.Hint: This version is an unsupported version.HBM can not give any support.File versions of catman have changed and the newest versions are not supported.

Put them in to your Matlab folder and add path to them in Matlab.Function call:a=IBWread(b);where b is path to the ibw file.
The data file is imported into 3 numeric arrays: Spectra, Wavenumbers and Time. Series_Info is a cell array containing the acquisition information from the file header. The spectral range and acquisition from this header info are used to calculate the Wavenumber and Time arrays.
Automated importation of sea surface temperature dataMatlab functions to import the high-resolution sea surface temperature data from the JPL OurOcean groupSummaryThe function getSST reads and store the sea surface temperature (SST) produced daily by the JPL OurOcean group [1]. The dataset is described in more details in Chao et al. [2]. The SST data are available on a grid of 0.009 degree, which represents a horizontal resolution of approximatively 1 km. In the documentation, the second example uses the function borders.m and/or bordersm.m [3,4]. This is the first version of the submission, some bugs may still be present. Credits should go to [1,2] for the dataset.ContentThe repository contains:The function getSST, which read the netcdf files and extract the SST data, time and corresponding coordinatesAn example within the Matlab livescript Documentation.mlxReferences[1] https://podaac.jpl.nasa.gov/dataset/JPL_OUROCEAN-L4UHfnd-GLOB-G1SST[2] Chao, Y., Z.

Overview : This example is explaining how to convert various native .NET data types to types compatible with MATLAB in Visual Studio. Basically, there are two main sections here which are 1) how to import correct data type to MATLAB function in Visual Studio.2) how to read the data type exported from MATLAB function in Visual Studio. For this example, it expects you know how to compile your MATLAB function to .net assembly, and know how to set up the configuration of Visual Studio to call MATLAB function. You may learn those through the link below:https://www.mathworks.com/help/compiler_sdk/gs/create-a-dotnet-application-with-matlab-code.html Highlights : Understand the the conversion of data type between .net and MATLAB in Visual StudioProduct Focus :MATLABMATLAB Compiler SDKThird-party Software required :Visual Studio (This example uses Visual Studio 2017)Written at 19 November 2018
