Please tell me the code and explain resultes if needed. Thank you

Create file Problem3.m and use appropriate MATLAB function (if applicable) to solve: (a) Find (A)^T and (B)^T (b) Find A^1 and B^-1 (c) Define column vector Q using the first column in matrix B and solve equation AX=Q (d) Show that AA^1 = I (identity matrix). Explain difference between standard matrix multiplication and element-wise multiplication ".*". Use MATLAB help for more information. (e) Show results for C=[A, A] and D=[A;A]. Explain results. A = [8 4 3 0 -2 1 1 9 5] B = [7 -5 4 1 5 3 6 -7 4]
