LOCALPEAKS Find local peaks and troughs in a vector

SYNTAX

peaks = localpeaks(X)
peaks = localpeaks(X,MODE)


DESCRIPTION

peaks = localpeaks(X) locates the local peaks in vector X.

peaks = localpeaks(X,MODE) locates local features specified by MODE. MODE can be set to 'peaks' (default), 'troughs' in order to identify local troughs or 'both' in order to identify both local peaks and troughs.
