- mars.tensor.special.kve(v, z, **kwargs)[源代码]¶
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)
- 参数
v (array_like of float) – Order of Bessel functions
z (array_like of complex) – Argument at which to evaluate the Bessel functions
- 返回
out – The exponentially scaled modified Bessel function of the second kind.
- 返回类型
ndarray
提示
Wrapper for AMOS 1 routine zbesk. For a discussion of the algorithm used, see 2 and the references therein.
