Syntax

public static double[] K(
	double x,
	int n
)

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

public:
static array<double>^ K(
	double x, 
	int n
)

static member K : 
        x : float * 
        n : int -> float[]

x: Type: SystemDouble
A double representing the argument for which the sequence of Bessel functions is to be evaluated.
n: Type: SystemInt32
A int which specifies the order of the last element in the sequence.

Type: Double
A double array of length n + 1 containing the values of the function through the series.

Remarks

This function uses $e^x K_{\nu+k-1}$ for $k = 1, \ldots, n$ and $\nu = 0$ . For the definition of
