Continuing the discussion of http://sourceware.org/ml/gsl-discuss/2007-q4/msg00038.html : Two files with the "diff -u" format are attached which implement Gaussian Hypergeometric Functions 2F1() for argument x=1. The implementation in hyperg_2F1.c has been changed to handle cases with negative values of the intermediate Gamma-functions correctly. All 4 tests added to test_hyperg.c are passed on my gcc 4.1.2 (i386 RedHat). On an unrelated issue, the testing for some 2F0() has been improved by insertion of more accurate results in test_hyperg.c. -- Richard J Mathar http://www.strw.leidenuniv.nl/~mathar
