Separate matrix each 3 columns and save outputs each iteration

Hello,

I have two issues:

I got a 30x90 matrix to be saparated every 3 columns each for loop iteration and save the each output into different files with different names in csv format.

Many thanks to those who can help me!

With some bold guessing, what "different names" means (better mention, what you want):

data   = reshape(1:30*90, 30, 90);  % Some test data
blocks = reshape(data, 30, 3, 30);
% Now blocks(:, :, k) is the k.th block of 3 columns

folder = 'D:\Your\Folder';
for k = 1:30
    Block = blocks(:, :, k);
    file  = sprintf('File%02d.mat', k);
    csvwrite(fullfile(folder, file), Block);
end
