Decide if these are matrix equivalent.

• $\begin{pmatrix}1&3&0\\ 2&3&0\end{pmatrix}$, $\begin{pmatrix}2&2&1\\ 0&5&-1\end{pmatrix}$

• $\begin{pmatrix}0&3\\ 1&1\end{pmatrix}$, $\begin{pmatrix}4&0\\ 0&5\end{pmatrix}$

• $\begin{pmatrix}1&3\\ 2&6\end{pmatrix}$, $\begin{pmatrix}1&3\\ 2&-6\end{pmatrix}$
