As you know we have quite extensive 3D plotting routines available
which runs in Matlab 5.2 as part of the SuperNEC interface (the
plotting routines are just matlab m files). Now I realise that you
wish to call them from your own program, and we have in fact done
something similar before.

We have called Matlab plot routines from within C code. We virtually
used Matlab to give us "debug information" ie instead of putting a
writeln statememt in the code you actually plot the intermediate
result by employing calls to Matlab. Derek Nitch will be able to give
you more details on how to do this, because I am sure you will be able
to do it from Pascal as well. Give him a shout at
d.nitch_at_ee.wits.ac.za if this would be of interest.
