ibetaci() double ibetaci ( double  a, double  b, double  q, double *  py  ) Normalized compliment of incomplete beta function 1 - Ix(a, b) inverse for x Purpose ibetaci returns a value x such that q = 1 - Ix(a, b), where q is the specified value of the normalized compliment of the incomplete beta function. Returns Value of x. Parameters [in] a Argument a. (a > 0) [in] b Argument b. (b > 0) [in] q Specified value of normalized compliment of incomplete beta function. (0 <= q <= 1) [out] py Returne 1 - x. The value returned in py is free from cancellation errors. Even if ibetaci returns 1, the value of py may be non-zero very small value. Error handling If a <= 0, b <= 0, q < 0 or q > 1, domain error (EDOM) occurs. Range error (ERANGE) may occur. Reference boost/math/special_functions
