I am trying to use the "findpeaks" function to find the peak in a set of data. I want to better understand how the function works. Please explain what is the purpose of the number "7000" in the line below? It finds several peaks when this number is low. ...
Besides complementing find peaks function with the possibility to find all peaks, both local maximums, and local minimums. This also provides a possible workaround for the findpeaks bug pointed out by PeakProminencesBugExample.mlx file. The output of the findAllPeaks funcition is a set of ...
This MATLAB function returns a vector with the local maxima (peaks) of the input signal vector, y.
function pmax = peakOfPeaks(nmax) B=[] for n=1:1:nmax A=[]; if n==1 A=1 else A=n end while n~=1 if mod(n,2)==1 A=[A,3*n+1]; n=3*n+1 else A=[A,n/2]; n=n/2 end end B=[B,max(A)] end pmax=max(B) end...
I'm assuming that xn in your loop above is the signal. You don't show us where xn comes from and it's not used in your call to findpeaks(). In your call to findpeaks, you use x. So If that is the case, then you don't need a loop.
figure tab1 = uitab('Title','Tab1'); ax1 = axes(tab1); plot(ax1,1:10) tab2 = uitab('Title','Tab2'); ax2 = axes(tab2); surf(ax2,peaks) Return all objects in the current figure and its descendants. h = findobj(gcf) ...

Find Peaks and Valleys: Use the find_peaks function from the scipy.signal module with appropriate parameters. Here's an example of how to do this: python import numpy as np import pandas as pd import matplotlib.pyplot as plt from scipy.signal import find_peaks, savgol_filter # Load your ...
I know that the function ThemeCopy findpeaks(data,'MinPeakProminence',12) could be used to find the peaks in my data that have a minimum prominence of 12, but I have ~10^8 data points, and that would take a long time for findpeaks to go over and do its work. I alr...
