Clear the workspace. Create a variable $$ and assign it to the following matrix value:

$=[75$

$23$

$18]$

Access the element $=2,$ and $=1($where $$ and $$ denoted the row and column, respectively$)$

and change it to a number twice its original value. Create a variable $$ and assign to it a

transpose of $.$ Verify that the fifth element of $$ is counted column$-$wise is the same as the

$=1,=3$ element using the function $().$
