besynud() double besynud ( double  nu, double  x  ) Derivative Y'ν(x) of Bessel function of the second kind of order ν Yν(x) (fractional order) Purpose besynud computes the derivative Y'ν(x) of the Bessel function of the second kind of order ν Yν(x). Returns Y'ν(x). Parameters [in] nu Order ν. [in] x Argument x. (x > 0) Error handling If x <= 0, domain error (EDOM) occurs. Range error (ERANGE) may occur. Reference boost/math/special_functions
