1. [2 points] Matrix-matrix products: Consider two vectors x=[1 2 3] and y=[4 5 6] and two matrices A=[7 8 9; 10 11 12; 13 14 15] and B=[1 2 3 ; 5 6 7; 8 9 10]. a. Find all legal MATLAB products (using * operator) between two vectors x and y that produce meaningful results. Show the results also. Exclude the array operator .*. b. Similarly, find all products between matrices A and B (and their transposes) and show the results. c. Find all legal products between vector x and matrix A.
