dde_solver

==========

This repository contains an updated version of the DDE_SOLVER Fortran

code written by S. Thompson and L. Shampine [1].

Major changes to dde_solver_m.f90

---------------------------------

* *Use assumed-shape arrays in all interfaces.*

  This fixed the segmentation faults that were occurring in the old version.

  (Users' old code will have to be updated to match the new interfaces.)

* *Removed ODEAVG,* and removed all the code in dde_solver_m.f90 related to

  averaging.  (This was done on the recommendation of S. Thompson.)

* *Added the function DDE_SOLVER_VERSION* that returns the software version.

The `examples/` directory has S. Thompson's original examples (with some

minor updates).

New unit tests are maintained in the `tests/` directory.
