$6.(10$ points$)$ Write MATLAB commands that do the following:

a$)$ Create the following matrix by using shorthand methods for creating vectors with

constant spacing. Do not type individual elements explicitly.

$]$

b$)$ Create a variable x by assigning the value in the $4$

th row and $3$

th column of A to x$.$ Note

that you cannot type the value explicitly.

c$)$ Create a row vector x$4$ by assigning the $4$

th row of A to x$4.$ Note that you cannot type

individual elements explicitly.

d$)$ Create a column vector y$3$ by assigning the $3$

rd column of A to y$3.$ Note that you cannot

type individual elements explicitly.

e$)$ Create a $2\backslash$times $4$ matrix named M that contains the elements of A in the $2$nd and the $3$

rd

rows, and the $3$

rd to the last columns. Note that you cannot type individual elements

explicitly.
