matlab.io.hdfeos.sw

Low-level access to HDF-EOS swath files

Description

To use these MATLAB® functions, you must be familiar with the HDF-EOS library C interface. In most cases, the syntax of the MATLAB function is similar to the syntax of the corresponding HDF-EOS library function. The functions are implemented as the package matlab.io.hdfeos.sw. To use this package, prefix the function name with a package path, or use the import function to add the package to the current import list, prior to calling the function, for example,

import matlab.io.hdfeos.*
fileId = sw.open(filename);

Access

matlab.io.hdfeos.sw.attachAttach to swath data set
matlab.io.hdfeos.sw.closeClose swath file
matlab.io.hdfeos.sw.createCreate new swath structure
matlab.io.hdfeos.sw.detachDetach from swath
matlab.io.hdfeos.sw.openOpen swath file
