Square Wave Generator

This is a simple function that returns an array of values that represent a square wave based on two essential inputs (total time and period) and four optional inputs (plot option, minimum amplitude, maximum amplitude, and resolution).

[f] = squareWave(time,per,plotChk,Amin,Amax,res)

Units are arbitrary, but time and amplitude are assumed.

The following examples illustrate its use:

[y] = squareWave(10,1);
OR
[y] = squareWave(10,1,1);
OR
[y] = squareWave(10,1,-1,1);
OR
[y] = squareWave(10,1,-1,1,1);
OR
[y] = squareWave(10,1,-1,1,1,1e5);
