$($c$)$ Consider the arrays B and C below:

$B=\{\begin{array}{cc}\text{:}[5,& 3]\\ 1,& 9\end{array},C=\{\begin{array}{cc}\text{:}[2,& 5]\\ 6,& 1\end{array}$

$($i$)$ Write a command to find the matrix $D=\{\begin{array}{cc}\text{:}[28,& 28]\\ 56,& 14\end{array}$ formed by matrix multiplication of the matrices $B$ and $C.$

$($ii$)$ Write a command to find the matrix $E=\{\begin{array}{cc}\text{:}[10,& 15]\\ 6,& 9\end{array}$ formed by elementwise multiplication of the matrices $B$ and $C.$Use matlab.
