% 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
|
|
|
|
% initialize local variables from input arguments
|
|
n = fs * duration; % number of samples (length of matrix)
|
|

|
