tmdsimpy.utils.harmonic.zero_crossing

tmdsimpy.utils.harmonic.zero_crossing(X, zero_tol=inf)

Finds the locations where the vector has zero crossings (sign changes).

Parameters:

X1D numpy.ndarray

Array to find approximate zero crossings in.

zero_tolscalar, optional

Require X at crossing to be less than this tolerance. The default is numpy.inf.

Returns:

TFnumpy.ndarray of bool

Has size the same as X, has True for indices of approximate zero crossings. True should always be the first index of the two indices that are before and after the crossing.

Notes

This function is not tested and should be used with care.
