$\begin{bmatrix}a11&a12\\a21&a22\\a31&a32\end{bmatrix}$

$\textup{a11}\rightarrow\textup{3*1+1}\rightarrow\textup{3+1=4}$

$\textup{a12}\rightarrow\textup{3*1+2}\rightarrow\textup{3+2=5}$

$\textup{a21}\rightarrow\textup{3*2+1}\rightarrow\textup{6+1=7}$

$\textup{a22}\rightarrow\textup{3*2+2}\rightarrow\textup{6+2=8}$

$\textup{a31}\rightarrow\textup{3*3+1}\rightarrow\textup{9+1=10}$

$\textup{a32}\rightarrow\textup{3*3+2}\rightarrow\textup{9+2=11}$

$\begin{bmatrix}a11&a12\\a21&a22\\a31&a32\end{bmatrix}$=$\begin{bmatrix}4&5\\7&8\\10&11\end{bmatrix}$
