Hi all,

The output of

help (special.hankel1) is not very informative. Help on ufunc:

hankel1 = <ufunc 'hankel1'>

Use a proper interactive shell, e.g.: http://ipython.scipy.org/ In [1]: import scipy.special In [2]: scipy.special.hankel1? Type: ufunc String Form: <ufunc 'hankel1'> Namespace: Interactive Docstring: y = hankel1(x1,x2) y=hankel1(v,z) returns the Hankel function of the first kind for real order v and complex argument z. (Not sure why the normal help does not show the docstring, In [3]: scipy.special.hankel1.__doc__ Out[3]: 'y = hankel1(x1,x2) y=hankel1(v,z) returns the Hankel function of the first kind for real order v and complex argument z.' ) TH, Arnd

I need the Hankel function of the first kind and zero order H_0^{(1)} (arg), where arg is a complex number.

How can I compute this Hankel function with scipy ?

Nils
