Problem 2: Work through the following MATLAB code by hand and fill in the table. Then check your results using MATLAB. M=[2 3 1;-446:-325; [nrows, ncols] size (M); Add = zeros (1,ncols); Total = 0; for col = 1 : ncols 1-10]; for row 1:nrows Add (col)A Add (col) + M(r ow, col) end Total-Total Add (col) end Add Total Before Loops [0 0 0] row
