H5-1: 10x1 + 2x2 - x3 = 27 - 3x1 - 6x22x3 = -61.5 x1 x2 + 5x3 = -21.5 (a) Solve the system of equations in H5-1 by using the Jacobi method. 8-8- Use X2 0as initial guess and perform three iterations. Also calculate the approximate relative errors. Please show all steps of your hand calculation. Develop a script M-file for the Jacobi method by modifying the script M-file for the Gauss-Seidel method that we developed in class. Test the code by solving H5-2(a). Save your script M-file as HW5_2bYourLastName.m.
