Helper function to create an event triggered matrix from a single channel of data. Usage: data=createdatamatpb(data,E,Fs,win) Inputs: data (input time series as a single vector) - required E (events to use as triggers) - required Fs (sampling frequency of data) - required win (window around triggers to use data matrix -[winl winr]) - required e.g [1 1] uses a window starting 1 sec before E and ending 1 sec after E if E is in secs Note that E, Fs, and win must have consistent units Outputs: data (event triggered data)
