I have mri frames that are in rgb and I want stack them in a 4d variable ( height x width x 3 channels x number of frames) so that I can view them as a montage.
How can i do this?

a = ones(5,6,3)+0;
b = ones(5,6,3)+1;
c = ones(5,6,3)+2;
stacked = cat(4,a,b,c);
% ^ concatenate along 4th dim
If the image sizes are not identical, you can pad them smaller ones to match the size of the larged one by using paddarray() and then use cat().
