Visualizing Systems
of Ordinary Differential Equations
University of Hartford Professor
Bob Decker's Mathlet allows you to visualize solutions of
2-dimensional systems of ordinary differential equations: plots both
solutions, phase portrait and the direction field.

How
to Plot Direction Fields using Mathematica
This website describes what Mathematica commands you need to
use to generate solution curves and direction fields, and how to plot
them together or separately.
-
How
to Plot Direction Fields using MATLAB
This website contains a very cool Matlab m-file called dirfield.m
which can be used to plot direction fields, solution curves, and
solution curves with direction fields. This involves both numerical
and symbolic solutions of DEs.
- Visualizing
direction fields and solution curves
This website allows for visualization of simple direction fields.
Numerically brittle.
- Fancier program for
visualizing
direction fields
This website (requires installation of Java 1.1.6) and uses DFIELD
to show direction fields and solution curves.
