Bessel.K Method (Double, Int32)

Evaluates a sequence of modified Bessel functions of the third kind with integer order and real argument.

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

Parameters

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

Return Value

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 , see below.
