scipy.special.k0e

scipy.special.k0e(x, out=None) = <ufunc 'k0e'>

Exponentially scaled modified Bessel function K of order 0

Defined as:

k0e(x) = exp(x) * k0(x).

Parameters

xarray_like

Argument (float)

outndarray, optional

Optional output array for the function values

Returns

Kscalar or ndarray

Value of the exponentially scaled modified Bessel function K of order 0 at x.

k0

Notes

The range is partitioned into the two intervals [0, 2] and (2, infinity). Chebyshev polynomial expansions are employed in each interval.

This function is a wrapper for the Cephes [1] routine k0e.
