Re: [vox-tech] slightly-OT : OSS to find peaks in dataset

Hi everyone,

I a wondering if anyone on the list has used some open source software to locate local maxima in a data set. would something like octave do this?

It would be easy to write a simple Octave function to find your local maxima. All local maxima would be where the slope changes sign, of course. Then you could threshold those maxima so that only peaks above a certain value are returned.

here is an example dataset, (plotted with gnuplot of course)
