# scipy.special.kve¶

scipy.special.kve(v, z) = <ufunc 'kve'>

Exponentially scaled modified Bessel function of the second kind.

Returns the exponentially scaled, modified Bessel function of the second kind (sometimes called the third kind) for real order v at complex z:

kve(v, z) = kv(v, z) * exp(z)

Parameters
varray_like of float

Order of Bessel functions

zarray_like of complex

Argument at which to evaluate the Bessel functions

Returns
outndarray

The exponentially scaled modified Bessel function of the second kind.
