Bessel_y1
Bessel-y1-func
Definition:
evaluates the Bessel function of the second kind,
, x > 0.
The approximation is based on Chebyshev expansions.
For more information please review the s17adc function in the NAG document.
Parameters:
- x (input, double)
- The argument x of the function.
- Constraint: x>0.0
(output, double)
- The approximation of the Bessel function of the second kind.
