Consider the two Matrices:

A $=[2454412],$ B $=[438$; $169$; $257]$

$$

$1.$ Assign a variable $"$x$1"$ to be the value in the second column of matrix A$.$

$2.$ Assign variable $"$x$2"$ to be the $3$rd column of matrix B$.$

$3.$ Assign variable $"$x$3"$ to be the $3$rd row of matrix B$.$

$4.$ Assign variable $"$x$4"$ to be the diagonal values in matrix B from top left to bottom right.$$

$5.$ Create a function file to evaluate the equation y$($x$)=$ x$^2$ Call your function file LN$\_$ModIII where LN is the first $5$ letters of your last name $($or up to $5$ letters if you have a short last name$).$ In your main program, test this function file with the values from #$4.($HINT: you will need to use $.^2$ instead of $^2$ in your function since we are calling in values from a matrix to square$)$
