$(50$ point$)$ Assume that $a,b,c$ and $d$ are defined as follows:

$a=\left[\begin{array}{cc}2& 1\\ -1& 4\end{array}\right],b=\left[\begin{array}{cc}-1& 3\\ 0& 2\end{array}\right],c=\left[\begin{array}{c}2\\ 1\end{array}\right],d=$eye$(2)$

Use MATLA to calculate the results of the following expressions if they are legal. If an

operation is illegal, explain why.

$a+b$

$a^{**}b$

a$.*$ d

$a^{**}c$

a $*$ c

$\frac{a}{\frac{?}{?}}b$

a$...$b

a$.^$b

$-\frac{11}{5}$

$\frac{5}{\frac{?}{?}}-11$

round $(-\frac{11}{5})$

ceil $(-\frac{11}{5})$

floor$(-11/5)$

can you do it in matlab please it has to be in matlab and screenshot the steps thanks
