WorksheetFunction.BesselI(Object, Object) Method

Definition

Returns the modified Bessel function, which is equivalent to the Bessel function evaluated for purely imaginary arguments.

public:
 double BesselI(System::Object ^ Arg1, System::Object ^ Arg2);
public double BesselI (object Arg1, object Arg2);
Public Function BesselI (Arg1 As Object, Arg2 As Object) As Double

Parameters

Arg1
Object

The value at which to evaluate the function.

Arg2
Object

The order of the Bessel function. If n is not an integer, it is truncated.

Returns

Remarks

If x is nonnumeric, BesselI returns the #VALUE! error value.

If n is nonnumeric, BesselI generates an error value.

If n < 0, BesselI generates an error value.

The n-th order modified Bessel function of the variable x is:
