3. Solve the following matrix problems by hand. Show your work step by step (write out each of the dot products). (a) A B where A = [2 6 3) and B 3 No 8 7 (b) B. A where A and B are the same as in Problem 1. [2 37 10 9 (C) AT. B where T denotes transpose and A = 4 5 and B = -6 -5 - 4 -3 2 1 4. Write a MATLAB script to verify your answers from 3a, 36 and 3c. Use the built-in MATLAB matrix operators (+,-.*,) and hardwire the necessary matrices into the program. 0
