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.
