Part $2$ Exercises

Recall that $a=$ last digit of your student ID$,b=$ second to last digit of your

student ID$,c=$ third to last digit of your student ID$,$ and $d=$ the sum of the

last three digits of your student ID$.$ Complete the following operations in

your script, making a new line for each operation.

$2$A$)$ Define the matrices M$1,$ M$2,$ M$3,$ and M$4$ in different lines in your

script so that they output the following matrices below $($the semicolons are

important; include them!$).$ You will be using these to answer the questions

that follow them.

$2$B$)P2B=8M1M2-4M2$

$2$C$)P2C=-3M{4}^2+7M3M2$

$2$D$)P2D=(5M2M3)(M{1}^3)\%$ matrix multiply in parentheses, elementwise

multiply between parentheses

$2$E$)P2E=\frac{6M4M3}{M{3}^2}\%$ matrix multiply in first parentheses,

elementwise otherwise

Once you have these operations written in proper MATLAB syntax, go to

your Editor menu and click Run. If there are values in your Command

Window for all operations without error messages, then your code has

successfully run! If you have error messages, read them carefully and try to

resolve them, then click Run again.
