AIZ, BIZ: two Fortran 77 routines for the computation of complex Airy functions
Two Fortran 77 routines for the evaluation of Airy functions of complex arguments $Ai(z)$, $Bi(z)$ and their first derivatives are presented. The routines are based on the use of Gaussian quadrature, Maclaurin series and asymptotic expansions. Comparison with a previous code by D.E. Amos (ACM Trans. Math. Soft. 12 (1986)) is provided.
