AdvancedMathPolyLog Method

public static double PolyLog(
	int n,
	double x
)

Public Shared Function PolyLog ( 
	n As Integer,
	x As Double
) As Double

public:
static double PolyLog(
	int n, 
	double x
)

static member PolyLog : 
        n : int * 
        x : float -> float 

Parameters

n

Type: SystemInt32
The order, which must be non-negative.

x

Type: SystemDouble
The argument, which must be less than or equal to one.

Return Value

The nth polylog of x is defined via the series:

Its name comes from the fact that this is a generalization of the logarithm series. For n = 1 it reduces to -log(1-x). For n = 2 it reduces to the DiLog(Double) function.

The polylogarithm function becomes complex for arguments larger than one.
