Can anyone explain how MinPeakProminence works in findpeaks?

I'm currently working on digital signal processing on PPG signal. Can anyone explain about minpeakprominence. I hace read through the examples given but i still dont have clear idea on that. thanks in advance.

'MinPeakProminence' is used when you want to return only those peaks that have a minimum relative importance of the value specified for this argument. Your best resource is the documentation which explains what this Name-Value pair does:

https://www.mathworks.com/help/signal/ref/findpeaks.html#input_argument_d0e61186

For an example, look through the "Prominence" section in the above link for description of the motivation behind this.

Also, as a reference, see the following example that returns peaks with a prominence of at least 4: https://www.mathworks.com/help/signal/ref/findpeaks.html#buhd30k

Hi again, but then what do you mean by 'minimum relative importance'? How do I relate the value to my signal to find?
