biplab chaki.mat

在 MATLAB Online 中打开

The program to find the peaks are as follows:

clc
a=importdata('biplab chaki.mat');
b=a.data;
x=b(25000:30000,1);
plot(x);
x(x<0)=[];
findpeaks(x);

Please stop bumping your question. If you do not get an answer, it is very likely that the question does not contain enough details to be answerd. Then adding information will help, while bumping without new details is a waste of time only - for you and for all readers.

What do you want to get? What is a Poincare plot with 4 points only?
