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:
