scipy.special.k1e

scipy.special.k1e(x) = <ufunc 'k1e'>

Exponentially scaled modified Bessel function K of order 1

Defined as:

k1e(x) = exp(x) * k1(x)

Parameters

xarray_like

Argument (float)

Returns

Kndarray

Value of the exponentially scaled modified Bessel function K of order 1 at x.

k1

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 k1e.
