Hi all,

Does anyone have an mfile that utilizes either gaussian or jacobian or LU factorization to solve multiple variable linear equations?

Thanks in advance :)

Yes. It is builtin in Matlab. According to the documentation of lu:

x = A\b;  % This is solved implicitely by:
[L,U] = lu(A);
y = L\b;
x = U\y;

If you want something else, please post more details.
