besj0 besj1 besjnu besy0 besy1 besynu

besynu() function besynu ( nu::Real  , x::Real    ) Bessel function of the second kind of order ν Yν(x) (fractional order) Purpose besynu computes the Bessel function of the second kind of order ν Yν(x). Returns Float64 Bessel function of the second kind of order ν Yν(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
