scipy.special.hankel2e#
- scipy.special.hankel2e(v, z, out=None) = <ufunc 'hankel2e'>#
Exponentially scaled Hankel function of the second kind
Defined as:
hankel2e(v, z) = hankel2(v, z) * exp(1j * z)
- Parameters:
- varray_like
Order (float).
- zarray_like
Argument (float or complex).
- outndarray, optional
Optional output array for the function values
- Returns:
- scalar or ndarray
Values of the exponentially scaled Hankel function of the second kind.
Notes
A wrapper for the AMOS [1] routine zbesh, which carries out the computation using the relation,
where is the modified Bessel function of the second kind. For negative orders, the relation
is used.
