+% GENERATE_puse: returns a matrix of sampled pulse wave
+
+% CONTRIBUTORS:
+% Brian Tran: Created the wave
+
+% DOCUMENTATION:
+% phase shift is in number of periods
+% fs is the sampling frequency: how many sample points per second
+% duration is time in seconds
+% duty is a number between 0 and 1
