Peak Finder
Determine whether each value of input signal is local minimum or maximum
Libraries:

Description
The Peak Finder block counts the number of local extrema in each column of a real-valued input signal. The block outputs the number of local extrema at the Cnt port. You can also configure the block to output the extrema indices, the extrema values, and a binary value indicating if the extrema are maxima or minima. To qualify as an extremum, a point has to be larger (or smaller) than both its neighboring points, so the block does not consider end points when counting extrema.
