MATLAB: Split 3d array into ‘i’ equal mat files

arraysmatfilesmatricesmatrixsplit

Hello All,
I have a matrix (called my_matrix) which is of size() 256 x 6 x 2000. Could you please let me know how to split this array into six separate .mat files (or some other easier way) each having 256 x 1 x 2000? I tried using for loop as below but it didn't work out.
    for i = 1:6
       filename[i] = 'my_data[i].mat';
       save(filename[i],'my_matrix(:,i,:)';'-mat');
    end
Thanks! \ksnf3000

See if this does what you want:
M = randi(99, 10,6, 15);                        % Create Matrix
C = num2cell(M, [1 3]);                         % Cell Array
for k1 = 1:size(C,2)
    filename = sprintf('my_data%d.mat', k1);
    my_matrix = squeeze(C{k1})'
    save(filename, 'my_matrix')
end
NOTE— I tested everything except the save call because I didn’t want to have to go back and delete those files. It should work as written.
