Definition

Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.1.5

LogGamma(Complex<Double>)	Returns the natural logarithm of the Gamma function for the specified complex number number.
LogGamma(Double)	Returns the natural logarithm of the Gamma function for the specified number.
LogGamma(Double, Int32)	Evaluates the natural logarithm of the Gamma function and returns the sign as an out parameter.

Returns the natural logarithm of the Gamma function for the specified complex number number.

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

Visual Basic

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

C++/CLI

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

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

Complex<Double>
The natural logarithm of the Gamma function for z

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

Returns the natural logarithm of the Gamma function for the specified number.

public static double LogGamma(
	double x
)

Visual Basic

Public Shared Function LogGamma ( 
	x As Double
) As Double

C++/CLI

public:
static double LogGamma(
	double x
)

static member LogGamma : 
        x : float -> float

Double
The natural logarithm of the Gamma function for x

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

Evaluates the natural logarithm of the Gamma function and returns the sign as an out parameter.

public static double LogGamma(
	double x,
	out int sign
)

Visual Basic

Public Shared Function LogGamma ( 
	x As Double,
	<OutAttribute> ByRef sign As Integer
) As Double

C++/CLI

public:
static double LogGamma(
	double x, 
	[OutAttribute] int% sign
)

static member LogGamma : 
        x : float * 
        sign : int byref -> float

Double
The logarithm of the Gamma function.
