How do you get to peaks in FFT?

Look for points where the value for the difference function goes from positive to negative. Those are your peak points. To find the most prominent peaks, compute the second order difference function at the points obtained from the first order difference and select the ones which are of highest magnitude.

How do you measure peak to peak in Matlab?

y = peak2peak( x ) returns the difference between the maximum and minimum values in x . y = peak2peak( x , dim ) computes the maximum-to-minimum differences of x along dimension dim .

What is prominence peak Matlab?

The prominence of a peak measures how much the peak stands out due to its intrinsic height and its location relative to other peaks. A low isolated peak can be more prominent than one that is higher but is an otherwise unremarkable member of a tall range.
