Webequations, iterative methods are preferable as iterative method are unaffected by round off errors to a large extent [4]. The well-known classical numerical iterative methods are the Jacobi method and Gauss-Seidel method. The rate of convergence, as very slow for both cases, can be accelerated by using SR technique [1,2]. But the speed WebFor example, for a two dimensional PDE problem, a 100×100 grid would be a perfectly reasonable size to consider. ... Figure 3 shows a the progress of the Jacobi method …
