Ibetac_sub() Sub Ibetac_sub ( Ret As  Double, A As  Double, B As  Double, X As  Double, Optional Info As  Long  ) Normalized compliment of incomplete beta function 1 - Ix(a, b) (Subroutine version) Purpose Computes the normalized compliment of the incomplete beta function 1 - Ix(a, b). 1 - Ix(a, b) = I(1-x)(b, a) Parameters [out] Ret Normalized compliment of incomplete beta function 1 - Ix(a, b). [in] A Argument a. (A >= 0, but A = B = 0 is not allowed) [in] B Argument b. (B >= 0, but A = B = 0 is not allowed) [in] X Argument x. (0 <= X <= 1) [out] Info (Optional) = 0: Successful exit. = -1: The argument A had an illegal value. (A < 0, A = B = 0) = -2: The argument B had an illegal value. (B < 0) = -3: The argument X had an illegal value. (X < 0 or X > 1) = 1: Floating point range error. Reference boost/math/special_functions
