Re: Modeling matrices in an XML environment

I did have some success doing number crunching with xml in the mix...
I was using an in-memory representation and tracking where all the
numbers I was manipulating were to perform the actual numerical
calculations in C++.  When certain events occurred, xslt was invoked
on the current state of the in-memory DOM, which would evaluate and
determine future trip/trap-points for the simulation.
Not optimal design...
