FindPeaks

FindPeaks[list] gives positions and values of the detected peaks in list.

FindPeaks[list,σ] finds peaks that survive Gaussian blurring up to scale σ.

FindPeaks[list,σ,s] finds peaks with minimum sharpness s.

FindPeaks[list,σ,s,t] finds only peaks with values greater than t.

FindPeaks[list,σ,{s,σs},{t,σt}] uses different scales for thresholding sharpness and value.

Examples

Find peaks in a list:

FindPeaks[{1, 3, 2, 5, 1, 4, 2}]
(* {{2, 3}, {4, 5}, {6, 4}} *)

Find peaks with minimum value threshold:

FindPeaks[{1, 3, 2, 5, 1, 4, 2}, 0, 0, 4]
(* {{4, 5}, {6, 4}} *)
