scipp.log#

scipp.log(x, *, out=None)#

Element-wise natural logarithm.

Parameters:

  • x (TypeVar(_T)) – Input data.

  • out (Variable | None, default: None) – Optional output buffer.

Returns:

TypeVar(_T) – Base e logarithm of the input.

Examples

Compute natural logarithm:

>>> import scipp as sc
>>> x = sc.array(dims=['x'], values=[1.0, 2.718, 7.389])
>>> sc.log(x)
<scipp.Variable> (x: 3)    float64  [dimensionless]  [0, 0.999896, 1.99999]

The input must be dimensionless and positive.
