A symmetrical square wave signal with amplitude $V$ and frequency $f$ can be described by the following series:

$x_{sq}(t)=\frac{4V}{}{\displaystyle \underset{n=1}{\overset{}{}}},3,5\frac{1}{n}sin(n2ft)$

EECS$3451$

Write a user$-$defined function "squarewave" in MATLAB that displays both the square waveform and its fundamental component. The function will also output the maximum instantaneous power of the fundamental component of $x_{sq}(t).$ The function will allow users to input the frequency of the square wave signal $(f),$ the amplitude $V,$ the number of terms to be used in the series in $(1),$ and the time array. Your output display must include a legend and a title.

Test your function by calling squarewave.m in your main M$-$file, and using the following parameters: $V=10,f=2Hz$ and $150$ terms of the series.
