COPPG_BEAT_DETECTOR - COPPG PPG beat detector.

COPPG_BEAT_DETECTOR detects beats in a photoplethysmogram (PPG) signal using the 'Percentile Peak Detector' beat detector

Inputs

• sig : a vector of PPG values

• fs : the sampling frequency of the PPG in Hz

Outputs

• peaks : indices of detected pulse peaks

• onsets : indices of detected pulse onsets
