3.5.2.5.19 Bessel_y0

Definition:

y0 = bessel\_y0(x) evaluates the Bessel function of the second kind,Y_0 , x > 0. The approximation is based on Chebyshev expansions.

For more information please review the s17acc function in the NAG document.


Parameters:

x (input, double)
The argument x of the function.
Constraint: x>0.0
y0 (output, double)
The approximation of the Bessel function.
