There is some strange logic in your code to account for the fact that you are performing your calculations using integer arithmetic. Say you have a 3x3 matrix in which the first two rows are: 4 6 5 1 2 3. When you compute del for col=0 and row=1, you will get: del = 1/4 = 0. With that, when you compute: mat [row] [j] -= del * mat [col] [j];
