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


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 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.
