Problem 4 (Writeup) In Activity 4, we used the tic and toc commands to time how long it takes to solve Ax-b using backslash with n = 1000, 1500, 2000, 2500, 3000, 3500, and 4000 equations. The matrix A and vector b were random matrices created using the commands A -rand (n) and b -rand (n, 1), respectively. We plotted the time versus n on a log-log scale. Re-create the plot from
