MATLAB: Matrix Operations

$\%$In this activity you will utilize MATLAB to evaluate sums, differences, scalar

$\%$products, and products of matrices.

$\%$Create the matrices A and $B.$

$\%$WARNING: Matrix operations are only possible on matrices of the appropriate sizes.

$\%$Find the sum of A and $B.$

$A+B$

$\%$Find the difference of A and $B.$

A $-$ B

$\%$Find the scalar product of $2$ times $A.$

$2*$A

$\%$ Find the product of A and $B.$

A$*$B

Use the following matrices for this activity.

$A=\left[\begin{array}{ccc}1& 2& 0\\ -1& -2& 3\end{array}\right],B=\left[\begin{array}{ccc}-2& 0& 3\\ 1& 3& 1\\ 0& 1& -1\end{array}\right],C=\left[\begin{array}{cc}3& 1\\ 2& -1\\ -1& 0\end{array}\right]$

Script $8$

$\%$ Create the matrices $A,B,$ and $C.$

$\%$WARNING: Matrix operations are only possible using matrices of the appropriate sizes.

$\%$Find the scalar product of $2$ times A$.$ Store this product in Ans$1.$

$\%$Find the product of A and B$.$ Store this product in Ans$2.$

$\%$Use the appropriate identity matrix to find the sum of Ans$2$ and AI$.$ Store this product in Ans$3.$

$\%$Use the appropriate identity matrix to find CI minus $2$ times the transpose of Ans$2.$ Store

$\%$this product in Ans$4.$
