Overview

Basic array operation literacy is a key skill for anybody hoping to become proficient in MATLAB. There is no shortcut to developing this skill; you simply have to practice and commit the operations and syntax to memory through continued exposure. For this problem, you will perform a series of short tasks that will help you solidify your understanding of array manipulation.

Problem Statement

Follow the steps below to create and manipulate a series of arrays.

a$)$ Create the array shown below and store it to a variable called Mat$1$

b$)$ Divide each element of Mat$1$ by $.$ Store your answer to a variable named A$.$

c$)$ You want to add $4$ to each element in the first row of Mat$1,$ subtract $1$ from each element in the second row of Mat$1,$ and keep the third row as$-$is$.$ Create a column vector that you can add to Mat$1$ to perform this task. Call your column vector B$.$

d$)$ Add B to Mat$1$ and store the answer to a new variable called D$.$

e$)$ Create a column vector from the second column of D$.$ Store your answer to a variable named E$.$

f$)$ Create a a row vector from the third row of D$.$ Store your answer to a variable named F$.$

g$)$ Create a $2$x$2$ matrix from the first two columns, and second and third rows, of D$.$ Store your answer to a variable named G$.$

h$)$ Create a new variable called H that has the same first colum as G$,$ but

$-$ Replace the element in the second column, first row of G with the element in the second colum, second row of Mat$1.$

$-$ Replace the element in the second row, second column of G with the element in the first colum, third row of Mat$1.$

As always, it is recommended to work in MATLAB then copy and paste your code to MATLAB Grader. Debugging is much easier in MATLAB than in the Grader portal.

Also, be sure to comment your script accordingly.

Note: Any locked lines in the provided script template cannot $($and should not$)$ be manipulated. These lines allow me to manipulate and test your answers properly. Some of these lines might be useful$/$necessary for you to understand $($e$.$g$.,$ defining an important variable for you$),$ but many of them will not.
