I try to find peaks of below array using the scipy find_peaks function.

Array = np.array([84.6345, 84.643, 84.6375, 84.568, 84.524, 84.5345, 84.5305, 84.548, 84.562, 84.6295, 84.668, 84.5795, 84.565, 84.5715])
peaks = find_peaks(Array)

But I got returned result with empty peak as below.

(array([ 1,  5, 10], dtype=int64), {})

Any advice or guidance on this would be greatly appreciated, Thanks.

CodePudding user response：

Your peaks are at elements 1, 5, and 10. What are you looking for? Do you want the actual values? That would be Array[peaks[0]].

The second return value only contains entries for specific argument combinations.
