I need help with number 4

a3. Using the Jacobi, Gauss-Seidel, and the SOR (co 1.4) iterative methods, write and run code to solve the follow- ing linear system to four decimal places of accuracy: [ 73-12]x11 -1] 0 3 8 1 4 2 -1 1 43 T4 Compare the number of iterations in each case. Hint: Here, the exact solution is x = (-1. I ,-1, 1)". (Continuation) Solve the system using the SOR iterative method with values of = 1(0.1)2. Plot the number of iterations for convergence versus the values of o. Which value of results in the fastest convergence? 4
