Syntax

AIRY(x)

specifies a numeric constant, variable, or expression.

The AIRY function returns the value of the Airy function. (See a list of References.) It is the solution of the differential equation

\begin{matrix} w^{(2)} - x w = 0 \end{matrix}

with the conditions

\begin{matrix} w (0) = \frac{1}{3 \frac{2}{3} Γ (\frac{2}{3})} \end{matrix}

and

\begin{matrix} w^{'} (0) = - \frac{1}{3 \frac{1}{3} Γ (\frac{1}{3})} \end{matrix}

The following SAS statements produce these results.
