AA is a $66$ matrix, Use MATLAB to define a submatrix "AAsub" between $4^{\text{I}}$ row and $6^{th}$ row, and between $1^{st}$ column and $3^{rd}$ column from the AA matrix with the remaining values of the matrix equal to $0.$

$($You cannot directly type in the values for the submatrix, must use MATLAB statement to define matrix AA$,$ then define the submatrix AAsub$)$

$AA=\left[\begin{array}{cccccc}1& 2& 3& 4& 5& 6\\ 7& 8& 9& 10& 11& 12\\ 13& 14& 15& 16& 17& 18\\ 19& 20& 21& 22& 23& 24\\ 25& 26& 27& 28& 29& 30\\ 31& 32& 33& 34& 35& 36\end{array}\right]$

$($Write MATLAB statement$)$
