Subject: [Bug-gsl] Bug in gsl_sf_hyperg_2F1 ??
Date: Sat, 8 Nov 2008 03:00:41 +0100
Hello,
I have tried to compute 2F1(11, -1 ; 11/2; 0.125) and I got an error message
(below is my sample program).
However 2F1(-1, 11 ; 11/2; 0.125) provides the right result 0.75
Am I wrong somewhere ?
I did not find any indication in archives.
Thank you for your help.
All the best,
Didier
