Definition:

evaluates the Bessel function of the second kind, , 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

(output, double)

The approximation of the Bessel function.
