Finite differencing techniques

RNPL (Rapid Numerical Prototyping Language) is a language for expressing
timedependent systems of PDEs using finitedifference techniques. Basic
information with examples is in Robert Marsa's thesis.
Supplementary information is here.

Ser is a visualization program built by Matt Choptuik to analyze
1dimensional time dependent data. Documentation and information on its
use:

A java variant of ser is jser. Basic information on it is
at intro.
