$\left[\begin{array}{ccc}0&-1&2\\2&1&1\\3&0&1\\3&7&1\end{array}\right] *\left[\begin{array}{cc}3&1\\2&1\\1&0\end{array}\right] =\left[\begin{array}{cc}0&-1\\9&3\\10&3\\24&10\end{array}\right]$

$\left[\begin{array}{ccc}1&1&3\\2&2&1\\3&2&1\end{array}\right] *\left[\begin{array}{ccc}1&-1&2\\-2&1&2\\1&0&-1\end{array}\right] =\left[\begin{array}{ccc}2&0&1\\-1&0&7\\0&-1&9\end{array}\right]$
