Q$2$: You are given the following:

$A=\left[\begin{array}{ccc}1& 2& 3\\ 4& 5& 6\\ 7& 8& 9\end{array}\right]$

$($a$)$ Use MATLAB to create an array B by copying the elements from the second and third columns of array A $(2$

pts$).$

$($b$)$ Use MATLAB to create an array $C$ by copying the elements from the first and second rows of array $A(2$ Point$).$

$($c$)$ Use MATLAB to create an array $D$ by copying the element from the array $A$ to let

$D=\left[\begin{array}{cc}4& 6\\ 7& 9\end{array}\right]$

You have to retrieve the value from array $A$ by using indexing matrix operation. $(4$ pts$)$

No credit if you use $D=\left[\begin{array}{ccc}{A}_{21}& A_{31}\text{;}{A}_{23}& A_{33}\end{array}\right]$
