SOLVED:(a) Write a MATLAB program that sets up a 15 ×40 matrix with entries 0 everywhere except for the values 1 in the positions indicated in the picture below. The upper-leftmost 1 is in position (2,2), and the lower-rightmost 1 is in position (13,39) . This picture was produced with the command spy(A). (b) Call svd to compute the singular values of A, and print the results. Plot these numbers using both plot and semilogy. What is the mathematically exact rank of A ? How does this show up in t
