This is a homework for MATLAB. Please answer using MATLAB functions and parameters. The answers are to be submitted as a .m script. Don't just list final answers.

Problem 4: In the following exercises, you will use the matrices below to perform matrix multiplication. The matrices have N x M dimensions, meaning N rows and M columns. Inner matrix dimensions need to match in order for the matrices to be multiplied. If MATLAB gives an error for the question asked, your answer should be a string 'error' (for example, p4a = 'error'). 18 31, 7 4 B= [2 5 107 3 8 5 [13] _ A= 1 [21] 2 5 3 7 a) Compute A2 and put the result in p4a. b) Compute A * B and put the result in p4b. c) Compute A* C and put the result in p4c. d) Compute A* D and put the result in p4d. e) Compute B * A and put the result in p4e. f) Compute B * D and put the result in p4f. g) Compute B *C and put the result in p4g. h) Compute C2 and put the result in p4h. i) Compute B * C * D and put the result in p4i. j) Is A * B equal to B * A? Put the answer in p4j. The answer should be logical, look up function isequal
