What is L?
L = 1000; % Length of signal
Is that how many data points you collected? Is that the time interval data points were collected over? Where does the 1000 come from?
Thanks!

It's the number of data points in the synthesised signal vector. It didn't come from anywhere - the person writing the documentation set it because she or he had to decide on some length for the signal.
