match peaks from plot
显示 更早的评论
v = hz1.Vdeg;
l = length(v);
t = 1:l(end);
plot(t,v);
[vmax,vindmax]=findpeaks(v,t);
[vmin,vindmin]=findpeaks(-v,t);
hold on
plot(vindmax,vmax,'o','MarkerFaceColor','r','MarkerSize',5);
plot(vindmin,-vmin,'d','MarkerFaceColor','g','MarkerSize',5);
figure
s = hz1.Dmm;
l = length(s);
t = 1:l(end);
plot(t,s);
[smax,sindmax]=findpeaks(s,t);
[smin,sindmin]=findpeaks(-s,t);
hold on
plot(sindmax,smax,'o','MarkerFaceColor','r','MarkerSize',5);
plot(sindmin,-smin,'d','MarkerFaceColor','g','MarkerSize',5);
I have these 2 peaks . how do I match the peaks from these two together ?

What exactly does "match" mean to you? And I see hundreds of peaks, not just two. I see two plots, each one having hundreds of peaks and hundreds of valleys. Please indicate the two peaks you want to "match" and mathematically define "match".
If you have any more questions, then ask them after you read this and clarify your question:

@Jes, look at Find local maxima - MATLAB islocalmax (mathworks.com). If its not available in your version of MATLAB you can eliminate the relatively negative findpeaks you found and thenn do a findpeaks on the reduced findpeaks.

@Jes, yes. Look at the last figure on that documentation page, I suspect that method will work for you to give a reasonable number of peaks.
