Visual C++

public static double BesselJ(
	int n,
	double x
)

Public Shared Function BesselJ ( _
	n As Integer, _
	x As Double _
) As Double

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

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

Parameters

n (Int32): The order parameter.

x (Double): The argument.

Return Value

The value of J_n(x).

Remarks

The Bessel functions of integral order occur in solutions to the wave equations with cylindrical symmetry. The regular Bessel functions are finite at the origin, and thus occur in situations where the wave equation is satisfied at the origin.
