scipp.isneginf

scipp.isneginf(x)

Element-wise isneginf (true if an element is a negative infinity).

Parameters:

x (TypeVar(VariableLikeType, Variable, DataArray, Dataset, DataGroup[Any])) – Input data.

Returns:

TypeVar(VariableLikeType, Variable, DataArray, Dataset, DataGroup[Any]) – Boolean variable indicating which elements are negative infinity.

Examples

>>> import scipp as sc
>>> import numpy as np
>>> x = sc.array(dims=['x'], values=[1.0, np.inf, -np.inf, 4.0], unit='m')
>>> sc.isneginf(x)
<scipp.Variable> (x: 4)       bool        <no unit>  [False, False, True, False]
