MATLAB: How to Detect Two maxima peaks

Question

Hi All

I am trying to detect the two peaks marked in blue arrow (in the image) along with its [value, location].

I have tried using max(), showpeaks(), etc., but they are detecting the other surrounding (insignificant) peaks along too.

Can someone help me with this?

Thanks.

Answer 1

Use the 'MinPeakHeight' and 'MinPeakDistance' name-value pair arguments.

Example —

[pks,locs] = findpeaks(YourSignal, 'MinPeakHeight',55, 'MinPeakDistance',700);

That will likely work for the signal you plotted, although you may have to experiment with the 'MinPeakDistance' value.
