Exercise 3 Say you have a variable, A, which is a 3-by-3 matrix you've created. Use the MATLAB Help Documentation to find the right function to use below. What MATLAB command can you use to find the determinant of A? What MATLAB command can you use to find the inverse of A? Say you had another 3-by-3 matrix, B.What MATLAB command can you use to find the cross product of A and B? Calculate the determinant of A= 1-4 -2 2 5 3 4 2 1 -2 What commands did you use? (To create A, and then to find the determinant). What is the determinant of A
