I am wondering how the value being calculated for "widths" and "proms" in Peak Prominences?
I am following "Peak Prominences".
Link: MathWorks
peak1.png
[pks,locs,widths,proms] = findpeaks(PeakSig,x);
widths
proms
widths
widths = 1×6
0.0154 0.0431 0.0377 0.0625 0.0274 0.0409
Why there is 6 value generated while only 2 peak (2 width) detected?
It same with proms:
proms
proms = 1×6
2.6816 5.5773 3.1448 4.4171 2.9191 3.6363
