Problem 38E
[M] Use at least three pairs of random 4 × 4 matrices A and B to test the equalities
(See Exercise 37.) Report your conclusions. [Note: Most matrix programs use .]
Exercise 37:
[M] Construct random 4 × 4 matrices A and B to test whether AB = BA. The best way to do this is to compute AB – BA and check whether this difference is the zero matrix. Then test AB – BA for three more pairs of random 4 × 4 matrices. Report your conclusions.
