Prob 3. 25pts Write a Matlab program to accept two integers M and N as input indicating the row and column numbers of a matrix. Generate and display a M x N random matrix by using the built-in function rand(M, N), and use for loop structures to determine the sum and average of each column and the overall matrix. Output your results using fprintf in complete sentences. You CANNOT use the built-in function sum or mean. Run your program with M-4, N = 5
