Project Requirements: $($ This project was discussed in class on $1/26/2024)$

Write a MATLAB code to plot the function:

$()=(+)()2()+()$

where a and b are integer constants.

Test and plot the results for the cases:

$($i$)$ a$=1,$ b $=1$;

$($ii$)$ a $=1,$ b $=-1$

It is recommended to use function calls for the ramp and step functions.
