[Help-gsl] Complete Gamma function for negative real argument and GSL

[Marc Normandin]

 Greetings,

  In my research an equation needs to be solved which involves the complete 
gamma function for negative argument. In the GSL documentation, I've only been 
able to find gamma functions for positive real argument. Is there a standard 
method to use GSL to compute values for the gamma function with negative 
argument, or must I write my own version of the complete gamma function by 
using the recursive property of it? That is, must I write a function to perform

Gamma(x) = Gamma(x+1)/x for -1 < x < 0

and extended it to further negative arguments?

I look forward to any responses,
   Marc.
