I was trying to find the peaks of my wave output, but for some reason it's not working, I don't know why.
vv = xlsread('1data.xlsx','A7:A100006')'; % voltage output
t = [-0.4:0.00001:0.59999]; % time
plot(t,vv);
findpeaks(vv,t);
it find pretty much all the points on the curve.

You likely have significant noise, and hte noise is being detected as peaks. Use the 'MinPeakProminence' name-value pair to return only the ones you want. (This will take some experimentation, so be patient.)
