QUESTION $1$

$Z=\left[\begin{array}{cccc}2& 2& 2& 0\\ 5& 6& 5& 6\\ 4& 5& 6& 7\\ 1& 2& 3& 4\end{array}\right]$

a$)$ Provide the code that will create the above matrix in MATLAB.

b$)$ Now provide the code that will extract the element in the third row of the fourth column of the matrix.

c$)$ Provide the code that will extract all the values in the fourth column of matrix. Store them as a variable named $($i$).$

d$)$ Provide the code that will extract extract all the values in the third row of matrix. Store them as a variable named $($ii$).$

e$)$ Provide the code that will multiply vector $($i$)$ with vector $($ii$).$ Store it as a variable named $($iii$).$

f$)$ Provide the code to transpose the matrix $($iii$)$ and store it as a matrix named $($iv$).$

State the purpose of the commands in the following formatted output:

fprintf$(\text{'}$A velocity of $8f\frac{m}{s}$ is calculated by dividing a distance of $\%f$ m over a

time period of $ f seconds $\frac{?}{?}$

${?}^{\text{'}},$ velocity, distance, time$)$

g$)\%$

h$)$ f

i$)ln$

j$)$ "velocity, distance, time"

k$)$ Change the code so that velocity will be displayed with one decimal, and both distance and time with no decimals. No

spacing must be added.
