- findpeaks - Find local maxima - MATLAB - MathWorks
You can first estimate the peak locations and amplitudes with findpeaks and then enhance your estimates with refinepeaks This example finds the peak amplitudes and locations of a synthetic noiseless pulse compression signal and uses refinepeaks to improve the estimates
- Peak Analysis - MATLAB amp; Simulink Example - MathWorks
Finding Peaks in Clipped or Saturated Signals You may want to consider flat peaks as peaks or exclude them In the latter case, a minimum excursion which is defined as the amplitude difference between a peak and its immediate neighbors is specified using the Threshold name-value argument
- Find Peaks in Data - MATLAB amp; Simulink - MathWorks
Locate the local maxima in a set of data and determine if those peaks occur periodically
- peaks2 - find peaks in 2D data without additional toolbox
Fast and effective 2D peak finding algorithm returning peak locations and values Accepts 2D arrays as an input (for instance, image acquired with a camera from some optics experiment) Various filters can be selected such as the minimal absolute value or threshold above the immediate surroundings etc
- Prominence - MATLAB amp; Simulink - MathWorks
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
