Find peaks in a matrix
zp = peak2(z, options) are the peak values in the 2-dimensional signal z.
[zp,ij] = peak2(z, options) as above but also returns the indices of the maxima in the matrix z. Use SUB2IND to convert these to row and column coordinates
'npeaks', N | Number of peaks to return (default all) |
'scale', S | Only consider as peaks the largest value in the horizontal and vertical range +/- S points. |
'interp' | Interpolate peak (default no interpolation) |
'plot' | Display the interpolation polynomial overlaid on the point data |
