Returns the modified Bessel function, which is equivalent to the Bessel functions evaluated for purely imaginary arguments.
Syntax
expression.BesselK (Arg1, Arg2)
expression A variable that represents a WorksheetFunction object.
Parameters
| Name | Required/Optional | Data type | Description |
|---|---|---|---|
| Arg1 | Required | Variant | The value at which to evaluate the function. |
| Arg2 | Required | Variant | The order of the function. If n is not an integer, it is truncated. |
Return value
Double
Remarks
If x is nonnumeric, BesselK generates an error value.
If n is nonnumeric, BesselK generates an error value.
If n < 0, BesselK generates an error value.
The n-th order modified Bessel function of the variable x is 
where Jn and Yn are the J and Y Bessel functions, respectively.
