Bessel_y1

Definition:

\(y1 = bessel\_y1(x)\) evaluates the Bessel function of the second kind,\(Y_1\) , 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

\(y1\) (output, double)

The approximation of the Bessel function of the second kind.
