Problem $4$

In matlab!!! Type in each matrix below. Reshape $x$ to be a $62$ matrix and $Y$ to be a column vector. Then concatenate the three matrices together to be a $93$ matrix named $W.$

$x=\left[\begin{array}{cccc}3& -2& 1& 2\\ 6& 8& -5& 12\\ 7& 9& 10& 1\end{array}\right],Y=\left[\begin{array}{ccc}6& 9& -4\\ 7& 5& 3\\ -8& 2& 1\end{array}\right],Z=\left[\begin{array}{cc}-7& -5\\ 10& 6\\ 3& -9\end{array}\right]$
