Fails to detect peaks at index 0

[Former user]

Peaks at index 0 are not found

eg

y = np.ones(10) y[0]=3 y[4]=2

peakutils.indexes(y) array([4], dtype=int64)

[Lucas Hermann Negri]

There are no peaks at the first or last positions, by definition (as the values outside the array are inexistent / undefined).
