Besknu() Function Besknu ( Nu As  Double, X As  Double, Optional Info As  Long  ) Modified Bessel function of the second kind of order ν Kν(x) (fractional order) Purpose Computes the modified Bessel function of the second kind of order ν Kν(x). Returns Double Modified Bessel function of the second kind of order ν Kν(x). Parameters [in] Nu Order ν. [in] X Argument x. (X > 0) [out] Info (Optional) = 0: Successful exit. = -2: The argument X had an illegal value. (X <= 0) = 1: Floating point range error. Reference boost/math/special_functions
