A. your program should start with a statement in comments at the top: "as a team, we have gone through all required sections of the tutorial, and each team member understands the material." b. creates 4 matrices, a, b, c, and d, of size 3x4, 4x2, 2x3, and 3x1. you can use randomized or hardcode values for the entries. output each of these matrices. c. computes the product e = abc and outputs the resulting matrix. (note: this is matrix multiplication not simple elementwise multiplication.) d. prints the transpose of e. e. solves the linear system ex=d for x (this is the solve command). print x
