PROBLEMS:

Matlab Environment: Undock and dock command window and take a screenshot for each case. $[$Two screenshots$]$ Procedure:

Click on the window.

Undock: $($Ctrl$+$Shift$+$U$)$

Dock: $($Ctrl$+$Shift$+$D$)$

Make a helloWorld script

When run, the script should display the following text:

Hello World! I am YOUR$\_$NAME

I am going to learn MATLAB!

Procedure:

Run Matlab, click File $$ New $$ Script $($Shortcut: Ctrl$+$N$).$

Save the file: "lastname$\_$firstname$\_$lab$1\_$helloworld.m$"[$Use this syntax for all problems$]$

Write these lines to the beginning of the script.

$\%$ lname$\_$fname$\_$lab$1\_$helloworld.m

$\frac{2}{\text{@}}$ Brief: This program displays two strings.

Use disp function.

Copy and paste your code to your lab report.

Scalar Variables: Make the following variables in Command Window. $($Take a screenshot after each command and add it to your lab report. Total: $4$ screenshots$)$

$a=10$

$b=2\mathrm{.}5**{10}^{23}$

$c=2+3i,$ where $i$ is the imaginary number

Introduction to Matlab Programming $-$ Lab Manual

$d=e^{\frac{2}{3}},$ where e is Euler's number.

Hint $(1)$: Carat sign: $a^b$ is defined using the carat sign between values $a^{{?}^{{?}^{?}}}b.$

Hint $(2)$: Get help on the MATLAB function exp using: $($a$)$ The "help exp" or $($b$)$ "doc exp" command typed in the Command Window.

Hint $(3)$: $\text{'}$pi$\text{'}$ is a keyword in Matlab. pi $==3\mathrm{.}1416.$

Scalar Equations: Using variables calculated in the previous problem, calculate equations below in Command Window: $($Take a screenshot after each command and add it to your lab report. Total: $3$ screenshots$)$

a$.x=\frac{1}{1+e^{(-\frac{a-15}{6})}}$

b$.y=(\sqrt[\phantom{2}]{a}+\sqrt[21]{b}{)}^{},$ recall that $\sqrt[g]{h}=h^{\frac{1}{g}}$

Vector Generation: In MATLAB a vector is a matrix with either one row or one column. The distinction between row vectors and column vectors is essential. Many programming errors are caused by using a row vector where a column vector is required, and vice versa.

i:k generates row vector containing integers from $i$ to $k$ with unit spacing $($ incremental of $1).$

i:j:k generates row vector containing integers from $i$ to $k$ with spacing of $j(j$ can be any number including real numbers$)$

Procedure:

Create a script "vector$\_$size.m$".$

Write these lines in your script.

Variables and Vectors

Assigns a single value to a

$m=1$;

Creates a vector from $0$ to $10$ with spacing of $1$ and then

$\frac{2}{6}$ assigns all these values to $x$

$x=0$:$10$

$\%$ Creates a vector from $0$ to $10$ with spacing of $0\mathrm{.}5$ and then

$$ assigns all these values to $x$

$y=0$:$0\mathrm{.}5$:$10$;
