This problem is using the program matlab

Write a program that for a square matrix subtracts the sum of the absolute value of the elements above the diagonal from the product of the absolute value of the diagonal elements. The input is matrix A, and the output is the difference described above. You can find an example calculation on page 356 of your textbook. [A] = [1 2 -4 5 -6 -7 8 -9 12 3 4 12 2 3 12 3] Your program must work for any size square matrix. You cannot use sort or sum or any such Matlab functions. If you are in any doubt about what functions you can use, please raise your hand
