a$)$ Create a $66$ matrix in the middle two rows, and the middle two columns are $3\text{'}$s and the rest areYou have to submit the matlab file in the form of:

YourName$\_$StudentID$\_$QuestionNumber; example:

Amer$\_20241423\_$Q$1.$

The commands should be submitted in the form of

$m.$ file $($type the commands for each question and save

it seperately$)$

a$)$ Amer went to the market. He bought $5kg$ of carrots $(4J\frac{D}{k}g),2kg$ of apples $),6$ lettuces

$(2$ for $4$JD$)$ and $6$ Pepsi $(2$JD each$).$ What is the total amount?

b$)$ Write the MATLAB command for the following line:

$Y=|x{e}^{ax}-cos(bx)|,$ for $a=11,b=$ and $x=\{2,4,6,8\}$

a$)$ Create a $66$ matrix in the middle two rows, and the middle two columns are $3^{\text{'}}s$ and the rest are

$4\text{'}$s$.$

b$)$ Write a MATLAB script file to plot the following on the same figure and on separate one $($use all

what you learned to express the label, title, color, $...$ etc.$)$ commands for drawing plot:

$f=3t^2+2t-0\mathrm{.}5$

$g=2tcos(t)$

where $t$ varies from zero to ten with $0\mathrm{.}5$step. The function $f$ should be in blue $0$ and $g$ in red $*.$

a$)$ Create a row vector start between $-10$ and $10$ with step $0\mathrm{.}5.$

b$)$ Create a row vector start between $-4$ and $7$ containing exactly $55$ values and store the result in

vector $x.$

Write a MATLAB command$($s$)$ to do the following:

$A=[0-1186$;$291310$;$-1543$;$91134]$

a$.$ Extract out the $3^{rd}$ row of matrix $A$ as a vector and assign this to vector $m.$

b$.$ Transpose matrix A and store the result in matrix $B.$

c$.$ Replace the $3^{rd}$ column of matrix A with $2^{nd}$ row of matrix $B.$

d$.$ Delete the $3^{rd}$ column of matrix $B.$

e$.$ Create a $2**3$ matrix $D$ consisting of all elements in the first two rows ans the last three

columns of matrix $A.$

f$.$ Find the maximum values in each column of matrix A$.$

g$.$ Find the minimum values in each row of matrix $A.$

h$.$ Sort each row of matrix $A$ in ascending order and store the result in $y.$

i$.$ Evaluate the sum of the $3^{rd}$ column of matrix $y.$

$4\text{'}$s$.$
