How to save variables in a loop by changing the names

Hi,

I have the following problem :

• I generate big 3D arrays on a powerful computer.
• I want to use these arrays on a computer with much less memory.

The solution I've come up with is to divide my big array in small arrays and save them to a mat file. For exemple :

In file named 'toto', I would have 'array_1', 'array_2'...'array_N'

I have tried something lile :

        for i=1:N
            array_i= array(:,:,i); %array is the big 3D array
            save('toto','array_i','-append');          
        end

But it obviously doesn't work since 'array_i' won't change at each loop.

Any idea?

Thank you

Ok, I use the eval function to solve the problem. Thanks!

There's a few good reasons to avoid doing it in that way.

You may be better off by writing a binary file.
