- Arg1
- Object
The value at which to evaluate the function.
- Arg2
- Object
The order of the function. If n is not an integer, it is truncated.
Returns
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.
