Please READ ALL INSTRUCTIONS BEFORE SUBMITTING !! MATLAB

Use the Gauss-Seidel method a) without relaxation and b) with relaxation (lambda = 1.2) to solve the following system of equations to a tolerance of 5%: 2x - 6y - Z = -38 -3x - y +7Z = -34 -8x + y - 22 = -20 Do this problem within a script file that does NOT call any other functions but rather use MATLAB as the wonderful calculator that it is. Loops and if/then statements are fine, just no function calls. For the sake of consistent grading, label your solutions in part a) as x1, y1, and z1; for part b) use x2, y2, and 22
