How can i import mass and stiffness matrices (MatK and MatK .TXT) to Matlab ?

Hi every one, i'm very new in MATLAB, i extracted mass and stiffness matrices from ansys workbench text files, and i want to import them to MATLAB.

load matm.txt

Error using load

Unable to read file 'matm.txt'. Input must be a MAT-file or an ASCII file containing numeric

data with same number of columns in each row.

Try importdata() or readmatrix(). Attach matm.txt if you still have trouble.

I have another problem, when i type

importdata('matlab.txt')

, all of matrix data shows in one column!!! Thanks in advance

Did you overlook my last sentence?

[Atif Laiche]

No, i did not !! sorry for my late response

[Image Analyst]

OK, since you saw my last sentence where I asked you to attach matm.txt, and since you did not attach it, I will assume that you chose not to attach it because you got it figured out already and no longer need our help. So I'm glad that you got it figured out.

@Image Analyst Please can explain how to use the attach matm.txt in this reference.

importdata(attach 'matlab.txt'); % Please just write it out it. Thank you.

@munachi Egbo to import matm.txt with importdata you'd do

data = import('matm.txt');

 importdata - Load data from file
    This MATLAB function loads data into array A.

    Syntax
      A = importdata(filename)
      A = importdata('-pastespecial')
      A = importdata(___,delimiterIn)
      A = importdata(___,delimiterIn,headerlinesIn)
      [A,delimiterOut,headerlinesOut] = importdata(___)

    Input Arguments
      filename - Name and extension of file to import
        character vector | string scalar
      delimiterIn - Column separator character
        character vector | string scalar
      headerlinesIn - Number of text header lines in ASCII file
        nonnegative scalar integer

    Output Arguments
      A - Data from the file
        matrix | multidimensional array | scalar structure array
      delimiterOut - Detected column separator in the input ASCII file
        character vector
      headerlinesOut - Detected number of text header lines in the input ASCII file
        integer
