[Bug-gsl] questions for Confluent Hypergeometric Function

[shaohao chen]

To gsl develop group:

The gsl has offered a lot ot useful functions for scientific reseach. I
usually calculate the special functions by gsl. But I have a problem now.

I have to calculate the Confluent Hypergeometric Function with complex
arguments in a C++ programme. I found the function "double gsl sf hyperg 1F1
(double a, double b, double x )" for double arguments, but is there any
function for complex arguments? If not, could you please consider to develop
such a function?  The Confluent Hypergeometric Function with complex
arguments is quite useful in many fields of physics. Thank you!

Best,
Shaohao
