12.2 (a)

Develop your own M-file function for the Gauss-Seidel method without relaxation based on Fig 12.2, but change the first line so that it returns the approximate error and the number of terations function [x,ea,iter]- GaussSeidel(A,b,es, maxit) Test it by duplicating Example 12.1 and then use it to solve Prob. 12.2a.
