Besynud_sub() Sub Besynud_sub ( Ret As  Double, Nu As  Double, X As  Double, Optional Info As  Long  ) Derivative Y'ν(x) of Bessel function of the second kind of order ν Yν(x) (fractional order) (Subroutine version) Purpose Computes the derivative Y'ν(x) of the Bessel function of the second kind of order ν Yν(x). Parameters [out] Ret The derivative Y'ν(x) of the Bessel function of the second kind of order ν Yν(x). [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
