650:231 M.E. Computational Analysis and Design, Fall 2010 Homework #3: Review of Linear Algebra 1. 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

Let x =[1 2 3] , y=[4 5 6] and z=[5 7 9]. Are three of them independent? Show which MATLAB command(s) can be used to find out the answer. Also show the results of using the command(s). b. Repeat the process for x =[1 0 3] , y=[4 5 6] and z=[5 2 9]....
