confirmed; it should handle the case of x<0 using A&S 13.1.3

Subject: [Help-gsl] Domain error in function gsl_sf_hyperg_U_int for a negative argument
Date: Mon, 26 Oct 2009 22:08:19 +0100


     I am trying to use the special function gsl_sf_hyperg_U_int(int 
n, int m, double x) and it seems it is implemented only for x being 
positive. Is it that true? I could not find any reference about that 
on the manual.  I have used mathematica and it is able to give a value 
for x < 0 what makes me think that the function is well defined on 
negative real numbers.

Thank you very much for your work and hlep,
