Hi, I have a matrix A = 169 x 606 and I want to convert each row into a 13 x 13 matrix? I know this is probably a simple operation, but I can't seem to get it to work. If anyone has any ideas it would be very much appreciated!
Thanks.

eg ( A - your matrix with size (169 x 4),)
for each column:
A = randi(3000,169,4);
out = reshape(A,13,13,[])
