Special.Gamma Method

public static Complex<double> Gamma(
	Complex<double> z
)

Public Shared Function Gamma ( 
	z As Complex(Of Double)
) As Complex(Of Double)

public:
static Complex<double> Gamma(
	Complex<double> z
)

static member Gamma : 
        z : Complex<float> -> Complex<float> 

Parameters

z  Complex<Double>

A complex number number.

Return Value

The formal definition of the Gamma function is as follows:

public static double Gamma(
	double x
)

Public Shared Function Gamma ( 
	x As Double
) As Double

public:
static double Gamma(
	double x
)

static member Gamma : 
        x : float -> float 

Parameters

x  Double

A real number.

Return Value

The Gamma function is a generalization to real numbers of the factorial of an integer. If x is a positive integer, then the following equality holds: \1

The formal definition of the Gamma function is as follows:
