Morse

A simple function used to encode ASCII characters into Morse code signals.

This takes a character string and encodes the string into a CW waveform with a specified sampling frequency. The function should be called as "Morse(string,wpm,fs)", string being a string of characters, wpm corresponding to words per minute, and fs representing the sampling frequency.
