besj0 besj1 besjnu besy0 besy1 besynu

besy1() function besy1 ( x::Real  ) Bessel functions of the second kind of order one Y1(x) Purpose besynu computes the Bessel function of the second kind of order one Y1(x). Returns Float64 Bessel functions of the second kind of order one Y1(x). Parameters [in] x Argument x (x > 0). Error handling If x <= 0, domain error (EDOM) occurs. Range error (ERANGE) may occur.
