Hi, I have been using the gsl_sf_hyperg_U function for a while and I found several bugs when calculating normal values. For example,
1) gsl_sf_hyperg_U(1, -500, 0.1) gives incorrect value: 9.3246e+03, which actually should be around 0.19. 2) Many domain error bugs. For example, gsl_sf_hyperg_U(1, -6.67, 1) should have value ~0.128 but will invoke domain error for gsl. Hope that you can further investigate this and come up with solutions. Thanks! Best Regards, Feng
