- function data=createdatamatc(data,E,Fs,win)
- % Helper function to create an event triggered matrix from univariate
- % continuous data
- % Usage: data=createdatamatc(data,E,Fs,win)
- % Inputs:
- % data (input time series as a column 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 * Fs samples before E and
- % ending 1*Fs samples after E.
- % Note that E, Fs, and win must have consistent units
- %
- % Outputs:
- % data (event triggered data)
- %
