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:

Parameters:	v : array_like of float Order of Bessel functions z : array_like of complex Argument at which to evaluate the Bessel functions
Returns:	out : ndarray The exponentially scaled modified Bessel function of the second kind.

v : array_like of float

Order of Bessel functions

z : array_like of complex

Argument at which to evaluate the Bessel functions

Returns:

out : ndarray

The exponentially scaled modified Bessel function of the second kind.
