scipy.signal.argrelmin

scipy.signal.argrelmin(data, axis=0, order=1, mode='clip')

Calculate the relative minima of data.

New in version 0.11.0.

Parameters :

data : ndarray

Array in which to find the relative minima.

axis : int, optional

Axis over which to select from data. Default is 0.

order : int, optional

How many points on each side to use for the comparison to consider comparator(n, n+x) to be True.

mode : str, optional

How the edges of the vector are treated. Available options are ‘wrap’ (wrap around) or ‘clip’ (treat overflow as the same as the last (or first) element). Default ‘clip’. See numpy.take

Returns :

extrema : ndarray

Indices of the minima, as an array of integers.

Notes

This function uses argrelextrema with np.less as comparator.
