Use #4 to answer 8-10. These are for matlab and I already did #4 but I dont know how to do 8-10. Please help!

4. Implement a matrix/vector multiplication routine in a function called, y-matrix vector mult (A, x) using only for-loops (there should bie only 2 loops used). Make the routine's matrices sizes generic so it will work with a matrix of any size. Create a 5-element column vector x full of random real-values and a 3x5 matrix A full of random real-values. Calculate the matrix y-Ax and display the vectors and the matrices
