BESSEL_Y1 intrinsic function

Standard: F77 F90 F95 F2003 F2008 F2018 Example program

---

＜Syntax＞

BESSEL_Y1 ( X )

X : Real, with value greater than zero;

Result : Same type and kind as X.

＜Semantics＞

The value of the result is an approximation to the Bessel function of the 2^nd kind, order 0, at the point X. Like many intrinsic functions, this is elemental; the result has the same shape as X, with the operation being applied elementwise.
