PeakDetector output arrays

[vix]

PeakDetector function search an input array for peaks (or valleys) and returns 3 arrays

• peakLocations
• peakAmplitudes
• peakSecondDerivatives

How are the peaks listed?

I mean: I think that every peak has the same position in all the 3 output arrays:

• peak #1 - peakLocations[0], peakAmplitudes[0], peakSecondDerivatives[0]
• peak #2 - peakLocations[1], peakAmplitudes[1], peakSecondDerivatives[1]
• ...

but how are the peaks listed?

Ordered by increasing peakLocations?

Ordered by increasing or decreasing peakAmplitudes?

[vix]

Could someone help with this question, please?

Hi vix,

because of some limitations in the functionality (see here) I ended up with writing my own function... and as you can see from my linked post my tests date back six years, so I forgot the details you are asking for...

Hi Wolfgang,

looking at your post I see you've been using ThresholdPeakDetector() - I didn't know this function exists.

On the other side, I've been using PeakDetector()

I don't know if the two functions behave somehow differently or if CVI2010 SP1 fixed the bug you found, but until now I haven't find any problem with PeakDetector().

Anyway, thanks to your suggestion I'll look deeper to avoid potential problems
