peakdetect.m generates and graphically displays the positive and negative polarity (concave down and up) peak index vectors of an input signal vector. Positive and negative polarity peaks occur at points of positive to negative and negative to positive slope adjacency, respectively. The typically rare contingencies of peaks occurring at the lagging edges of constant intervals are supported.

Example:

[p,n]=peakdetect([-1 -1 0 1 0 1 0 -1 -1])

p =

4 6

n =

1 5 8
