Gauss-Seidel iterval method using Matlab

[Austris]

Hello.

I am new in matlab. And I wonder how to solve equations using gauss-seidel iteration method.
Theoreticaly I understand how this method is working, but can't get how write script in matlab.

It can be great if somebody can give a explanation for this problem.

Well, what have you done so far? Can you make a jacobi method?
