Math 455 HW 13
Problem 1.
Consider the following system of linear equa?ons
If a=c=1, b=4, then
(a) Solve the linear system by Gaussian elimina?on method and Gaussian elimina?on method with par?al pivo?ng for n=10, 50 and 250. Which one is beQer and explain the reason?
(b) Solve the linear system by using Jacobi, Gauss-Seidel and SOR methods for n=10, 50 and 250. Which one is beQer and explain the reason? Find the op?mal ω for the SOR method.
If a=c=-1, b=2, then
