How does Find_peaks work?
Find peaks inside a signal based on peak properties. This function takes a 1-D array and finds all local maxima by simple comparison of neighboring values. Optionally, a subset of these peaks can be selected by specifying conditions for a peak's properties.
What does Find_peaks return?
pks = findpeaks( data ) returns a vector with the local maxima (peaks) of the input signal vector, data . A local peak is a data sample that is either larger than its two neighboring samples or is equal to Inf . The peaks are output in order of occurrence.
What is prominence in find peaks?
The prominence of a peak measures how much the peak stands out due to its intrinsic height and its location relative to other peaks. A low isolated peak can be more prominent than one that is higher but is an otherwise unremarkable member of a tall range.
