Let

be the unit square,

Consider the two-dimensional Laplace equation

Write a MATLAB function [x y u] = laplacej(g,n,maxiter) that uses the Jacobi iteration to approximate the solution to Equation 20.27 and creates a surface plot.

The exact solution with

Plot the solution using the MATLAB function ezsurf.

Plot the solution by applying laplacej with

and numiter
