Beta Cbeta Clnbeta Lnbeta

Beta() Function Beta ( A As  Double, B As  Double, Optional Info As  Long  ) Beta function B(a, b) Purpose Beta computes the beta function at a and b. B(a, b) = Γ(a)Γ(b)/Γ(a + b) Returns Double Beta function B(a, b). Parameters [in] A Argument a. (A > 0) [in] B Argument b. (B > 0) [out] Info (Optional) = 0: Successful exit. = -1: The argument A had an illegal value. (A <= 0) = -2: The argument B had an illegal value. (B <= 0) = 1: Floating point range error.
