MATLAB: How to save variables in a loop by changing the names

matfilesave

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
