Besynd_sub() Sub Besynd_sub ( Ret As  Double, N As  Long, X As  Double, Optional Info As  Long  ) Derivative Y'n(x) of modified Bessel functions of the second kind of order n Yn(x) (Subroutine version) Purpose Computes the derivative Y'n(x) of the modified Bessel function of the second kind of order n Yn(x). Parameters [out] Ret The derivative Y'n(x) of the modified Bessel function of the second kind of order n Yn(x). [in] N Order n. [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
