How do you use Findpeaks function?

Use findpeaks with default settings to find the peaks of the signal and their locations. [pks,locs] = findpeaks(PeakSig,x); Plot the peaks using findpeaks and label them. Sort the peaks from tallest to shortest.

How does SciPy signal Find_peaks work?

Find peaks inside a signal based on peak properties. This function takes a 1-D array and finds all local maxima by simple comparison of neighboring values. Optionally, a subset of these peaks can be selected by specifying conditions for a peak's properties.

What is peak finding?

If you are equal and greater than the elements on left and right side than you are the peak. In case of the edges, you only have to look at only one side. For example, position 9 is a peak if i >= h. So the problem we solve right now is represented as “Find a peak if exists”.
