Syntax

C#
public static double Beta(
	double a,
	double b
)
Visual Basic (Declaration)
Public Shared Function Beta ( _

) As Double
Visual C++
public:

a
Type: System..::.Double
A double value.
b
Type: System..::.Double
A double value.

Return Value

A double value specifying the Beta function.

Remarks

The Beta function is defined to be

\beta (a,b) = {{\Gamma (a)\Gamma (b)} \over {\Gamma (a + b)}} = \int_0^1 {t^{a - 1} } (1 - t)^{b - 1} dt

See Gamma for the definition of \Gamma \left( x \right).

The method Beta requires that both arguments be positive.
