ATMAX_BEAT_DETECTOR - ATmax PPG beat detector.

ATMAX_BEAT_DETECTOR detects beats in a photoplethysmogram (PPG) signal using the 'Adaptive Threshold Method (Vmax)' 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

• Dong Han - wrote the 'my_peak_compare_Shin_2009' function.

• Peter H. Charlton - did very little, just wrote this wrapper (which detects onsets given the peaks provided by the code)
