Does GSL or IMSL or GMP or MPFR have high precision hypergeometric function 2F1?
Hi all, I am looking for a high/multiple precision hypergeometric function 2F1(a, b, c, z) implementation. My application needs b and c to be very large, and it is beyond the range of double precision. More specifically, I hope I will be able to looking into the multiple precision implementation of the hypergeometric function 2F1(a, b, c, z) and change the power series a0+a1*z+a2*z^2+a3*z^3+... into a0+a1*z1+a2*z2+a3*z3+... where z1, z2, z3, ... are user supplied high precision numbers. The whole evaluation of the hypergeometric function has to be extremely fast for my application. Could anybody shed some lights? Thanks a lot!
