I don't have an office on campus. The best way to contact me is by email:

The commented lines in the MATLAB code show how the function is used. The results are: $x=[1.3333,3.1667,1.5000,-6.0000]$.

Also, the $A$ and $b$ (denoted as $C=[Ab]$ below) are updated as:

$$\begin{array}{r}{C}^1=\left[\begin{array}{ccccc}1& 1& 1& 1& 0\\ 0& -3& -3& -3& 4\\ 0& 3& -5& 0& 2\\ 0& -6& -6& -4& -4\end{array}\right]\end{array}$$

$$\begin{array}{r}{C}^2=\left[\begin{array}{ccccc}1& 1& 1& 1& 0\\ 0& -3& -3& -3& 4\\ 0& 0& -8& -3& 6\\ 0& 0& 0& 2& -12\end{array}\right]\end{array}$$

$$\begin{array}{r}{C}^3=\left[\begin{array}{ccccc}1& 1& 1& 1& 0\\ 0& -3& -3& -3& 4\\ 0& 0& -8& -3& 6\\ 0& 0& 0& 2& -12\end{array}\right]\end{array}$$

The final result for $x=[1.333,3.167,1.5,-6]$.
