How to reshape and reorder a 5D arrays to 4D arrays?

Hello

I'm managing 192x192x20x8x2 dimension arrays. In my problem, I need to reshape the 5D array to 4D, and re-ordering the third dimension.

For example, I need to reorder the 5D arrays from [ : , : , 1 : 2 : 39 , : , 1 ] and [ : , : , 2 : 2 : 40 , : , 2 ] to the 4D arrays [ : , : , 1 : 40 , : ]

How could I do it? Thanks a lot!

Let A - your 5D array:

k = size(A);
out = zeros(k(1:end-1).*[1,1,2,1]);
out(:,:,1:2:end,:) = A(:,:,:,:,1);
out(:,:,2:2:end,:) = A(:,:,:,:,2);
