Subject: ZVODE, a Double Precision Complex ODE Solver

Of the many solvers freely available for ODE initial value problems,
there seem to be very few, if any, for the case of double precision
complex dependent variables, even though there have been occasional
user calls for this functionality.  (Of course a complex system can be
treated as a real system of twice the size, but direct treatment as a
complex system is preferable.)  I have provided such a solver: ZVODE.

ZVODE is a straightforward modification of the Fortran ODE solver DVODE, for
double precision real systems, making it part of a trio, SVODE/DVODE/ZVODE.
ZVODE is available in two locations:
(1) Netlib, in /ode (see file zvode.f), and
(2) the LLNL CASC software site, www.llnl.gov/CASC/software.html (see VODE).
The latter site also includes a demonstration program, zvdemo.
