Title: MuPAD - An Open Computer Algebra System and its Approach of
         Software Integration
Authors: Ralf Hillebrand, Frank Postel

The talk gives a brief introduction to the general purpose Computer Algebra
System MuPAD and its concepts of domains and using library packages and the
technology of dynamic modules for flexible and efficient software integration
in MuPAD.  With dynamic modules, simple C or C++ functions as well as complete
software packages can be linked into MuPAD.  This is a very flexible and
efficient alternative to interprocess communication for many applications.  We
present some examples: integrating C/C++ code for numerical calculations
(Singular), using MP / Singular for polynomial computations and using PVM for
distributed computations (macro parallelism).
