## Meep

Meep (or MEEP) is a free open-source finite-difference time-domain (FDTD) simulation software package developed at MIT to model electromagnetic systems.

## Toy Fdtd Software

The Toy Fdtd site contained some nice introductory and well commented software. The original site disappeared, but an archive is here:

## Maxima

Maxima is a system for the manipulation of symbolic and numerical expressions,

including differentiation, integration, Taylor series, Laplace transforms, ordinary

differential equations, systems of linear equations, and vectors, matrices, and tensors.

Maxima produces high precision results by using exact fractions and arbitrarily long

floating point representations, and can plot functions and data in two and three dimensions.

## Gnuplot

Gnuplot is a portable command-line driven interactive data and function plotting utility

for UNIX, IBM OS/2, MS Windows, DOS, Macintosh, VMS, Atari and many other platforms.

It was originally intended as to allow scientists and students to visualize mathematical functions and data.

Gnuplot has been supported and under development since 1986

## LaTeX

LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation.
