I have a matrix 'M(1715*3849)' I want to reshape it to a Matrix that the size of the column can divisible with 12. How can I do it?
Thanks in advance.

It will append columns with nan value
M = rand(1715, 3849);
extra_columns = ceil(size(M,2)/12)*12 - size(M,2);
M = padarray(M, [0, extra_columns], nan, 'post');
size(M,2)/12
Result:
ans =
321
