Provide the matlab code of the following: $(2$D Plots$)$ Let $x$ be a row vector all integers from $1$ to $10.$ The following functions of $x$ are

defined:

$y_1=sin5x$

$y_2=e^{-2x}$

Use the hold on$/$off command, plot $y_1$ and $y_2$ against $x.$ Use the following specifications:

For the $y_1$ plot Use green dashed lines of size $2.$ Also use pentagram markers of size $12,$

with face color of red and edge color of blue.

For the $y_2$ plot: Use the stairs plot with a line width of $2$ and a magenta line color.

Title of the Graph: SAMPLE PLOTS

Set the Font Size of the title to $18$ and its color to red.

$x-$ axis label: Samples

$y-$axis label: Functions

Set the Font Size of the $x-$ axis and $y-$ axis labels to $12$ and their color to blue.

Add a legend to the graph. The legend for $y_1$ is Function $1$ and the legend for $y_2$ should

be Function $2.$

$(3$D Plots$)$ Given the expression:

$z=\frac{y^2}{4}-2sin(1\mathrm{.}5x)$

Create a $3$D plot for the domain $-3x3$ and $-3y3$ with a spacing of $0\mathrm{.}5$ for both $x$

and $y$ using,
