how can I save from MATLAB

I have generated a large number of matrices in MATLAB , all these are appear on the MATLAB comand window as;

Matrix 1 =

     1     2     3
     2     3     1
     3     1     2
Matrix 2 =

     1     2     3
     3     1     2
     1     3     2

and so on , How can I save all these in one file, and how can I used the resulting matrices in my latter work?

Can you post the code which generated these matrices? YOu should not generate them into different variables......you shall consider generating into a 3D matrix.

[Domanic]

With your variables, you could save them using:

save('filename.mat','Matrix1','Matrix2',...)

However, as KSSV points out, it would be best to save these matrices as a single variable, or a cell array of matrices. If you're stuck with those matrix names, you can use the function 'eval' to automate saving.

"If you're stuck with those matrix names, you can use the function 'eval' to automate saving."

Why bother? It is much simpler to use save and a regular expression:

save('file.mat','-regexp','Matrix\d+')

eval is what beginners use to force themselves into writing slow, complex, buggy code:

The best solution though, as others have already noted, is to not use numbered variables.

If the variables are inside the MATLAB workspace you can use the command

 save('MyFileName.mat');

when you want to restore the variables you can use the command.

 load('MyFileName.mat');
