Algorithm 822

Algorithm 822: GIZ, HIZ: two Fortran 77 routines for the computation of complex Scorer functions. Two Fortran 77 routines for the evaluation of Scorer functions of complex arguments Gi(z), Hi(z), and their derivatives are presented. The routines are based on the use of quadrature, Maclaurin series, and asymptotic expansions. For real z, comparison with a previous code by A. J. MacLeod [1994] is provided.
