numpy.lib.scimath.power
-
lib.scimath.power(x, p)
[source] -
Return x to the power p, (x**p).
If
x
contains negative values, the output is converted to the complex domain.- Parameters
-
-
xarray_like
-
The input value(s).
-
parray_like of ints
-
The power(s) to which
x
is raised. Ifx
contains multiple values,p
has to either be a scalar, or contain the same number of values asx
. In the latter case, the result isx[0]**p[0], x[1]**p[1], ...
.
-
- Returns
-
-
outndarray or scalar
-
The result of
x**p
. Ifx
andp
are scalars, so isout
, otherwise an array is returned.
