Hyp2f1_sub() Sub Hyp2f1_sub ( Ret As  Double, A1 As  Double, A2 As  Double, B As  Double, Z As  Double, Optional Info As  Long, Optional Abserr As  Double  ) Hypergeometric function 2F1(a1, a2; b; z) (Gaussian hypergeometric function) (Subroutine version) Purpose Computes the hypergeometric function 2F1(a1, a2; b; z). 2F1(a1, a2; b; z) = Σ(a1)k*(a2)k/(b)k * z^k/k! (k = 1 to ∞) Parameters [out] Ret Hypergeometric function 2F1(a1, a2; b; z). [in] A1 Argument a1. [in] A2 Argument a2. [in] B Argument b. [in] Z Argument z. [out] Info (Optional) = 0: Successful exit. = -1: The argument A1, A2, B or Z had an illegal value. (domain error) = 1: Floating point range error. [out] Abserr (Optional) Estimated absolute error. Note This function computes by using Hyppfq. Depending on the values of arguments domain error may occur. Reference boost/math/special_functions
