WBeta WLnbeta

WLnbeta() Function WLnbeta ( A As  Double, B As  Double  ) Logarithm of beta function ln(B(a, b)) Purpose WLnbeta computes the logarithm of the beta function ln(B(a, b)). ln(B(a, b)) = ln(Γ(a)Γ(b)/Γ(a + b)) Returns Logarithm of the beta function ln(B(a, b)). Parameters [in] A Argument a. (A > 0) [in] B Argument b. (B > 0)
