Finite

Free Finite Element Package is a modular collection of C libraries which contain numerical methods required when working with linear and quadratic finite elements in two dimensions. FFEP works on GNU/Linux and is portable to every system where MEML (i.e. LAPACK and BLAS) are available. The goal...

This script shows a Finite State Machine (FSM) that can be used for small parsing tasks. The code is quite simple. The bulk of it is comments. In addition to state this FSM also maintains a user defined "something". This "something" is effectively memory, so this FSM could be considered a...

Simulation of a gaussian pulse propagated in free space through 1000 um, using finite differences.Just run the script and you'll get a surface which is made up of the pulse propagated at 1 um steps.
