np_any_axis0

dtaianomaly.utils.np_any_axis0(x)[source]

Numba implementation for np.any(x, axis=0).

Iterates over the columns of the given matrix and applies a logical OR to it. Thus, if any value in column \(j\) is True, then the value at position \(j\) in the output will be True.

Parameters:

xnp.ndarray of shape (N, M): The array on which the numpy-call should be applied.

Returns:

np.array of shape (M,): Identical as np.any(x, axis=0).

Examples

>>> import numpy as np
>>> from dtaianomaly.utils import np_any_axis0
>>> np_any_axis0(np.array([[True, False, True, False], [False, False, True, True]]))
array([ True, False,  True,  True])
