Define

$x_1=\{[2],[8],[4]\},$ and $,x_2=\{[9],[1],[5]\}$

Write Matlab code to calculate the following. Turn in your code listing and the Matlab

results. You may cut and paste if you need to$.$

Also perform the calculations yourself on paper showing your work as you go$.$

$($a$)$ The matrix product $x_1^T{x}_2$

$($b$)$ The matrix product $x_1{x}_2^T$

$($c$)$ The column array, each of whose elements is the product of the corresponding elements

of $x_1$ and $x_2.$
