ModifiedBesselI Method (nu, x)

Computes the regular modified cynlindrical Bessel function.

Declaration Syntax

Visual Basic

Visual C++

public static double ModifiedBesselI(
	double nu,
	double x
)

Public Shared Function ModifiedBesselI ( _
	nu As Double, _
	x As Double _
) As Double

public:
static double ModifiedBesselI(
	double nu, 
	double x
)

static member ModifiedBesselI : 
        nu:float * 
        x:float -> float

Parameters

nu (Double): The order parameter.

x (Double): The argument, which must be non-negative.

Return Value

The value of I_ν(x).

Remarks

The modified Bessel functions appear as the solutions of hyperbolic differential equations with cylindrical or circular symmetry, for example the conduction of heat through a cylindrical pipe.

The regular modified Bessel functions are related to the Bessel fuctions with pure imaginary arguments.

The regular modified Bessel functions increase monotonically and exponentially from the origin.
