Function rgsl::hypergeometric::hyperg_2F1

pub fn hyperg_2F1(a: f64, b: f64, c: f64, x: f64) -> f64

This routine computes the Gauss hypergeometric function 2F1(a,b,c,x) = F(a,b,c,x) for |x| < 1.

If the arguments (a,b,c,x) are too close to a singularity then the function can return the error code MaxIter when the series approximation converges too slowly. This occurs in the region of x=1, c - a - b = m for integer m.
