Hey, no fair asking the same question twice, Dau. It wastes our time when we inadvertently duplicate answers, as I just did here.

If these values A, B, C, etc. as shown are in a 31 x 24 matrix called Mat1, then do:
Mat2 = reshape(Mat1',[],1);

Change the places between the first row and third column elements of matrix A. How can I do this?
