peak

Find peaks in vector

yp = peak(y, options) are the values of the maxima in the vector y.

[yp,i] = peak(y, options) as above but also returns the indices of the maxima in the vector y.

[yp,xp] = peak(y, x, options) as above but also returns the corresponding x-coordinates of the maxima in the vector y. x is the same length of y and contains the corresponding x-coordinates.

Options

'npeaks', N Number of peaks to return (default all)
'scale', S Only consider as peaks the largest value in the horizontal range +/- S points.
'interp', N Order of interpolation polynomial (default no interpolation)
'plot' Display the interpolation polynomial overlaid on the point data
