SfunLogBeta Method
Returns the logarithm of the Beta function.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
Syntax
public static double LogBeta(
	double a,
	double b
)

Parameters

a
Type: SystemDouble
A double value.
b
Type: SystemDouble
A double value.

Return Value

Type: Double
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.
