Sfun.LogBeta Method

Returns the logarithm of the Beta function.

public static double LogBeta(
double a,
double b
);

Parameters

a: A double value.
b: A double value.

Return Value

A double value specifying the natural logarithm of the Beta function.

Remarks

Method LogBeta computes ${\rm ln} \, \beta \left( {a,b} \right) = {\rm ln} \, \beta \left( {b,a} \right)$ . See Beta for the definition of $\beta \left( {a,b} \right)$ .

LogBeta is defined for $a \gt 0$ and $b \gt 0$ . It returns accurate results even when a or b is very small. It can overflow for very large arguments; this error condition is not detected except by the computer hardware.
