dfield and pplane
the java versions
dfield and pplane
dfield (direction field) and
pplane (phase plane) are software programs for the interactive analysis of ordinary differential equations (ODE).
The software is described in detail in the manual
Ordinary Differential Equations using MATLAB.
Additionaly, several textbooks on differential equations refer to and use
pplane. Among them are
Differential Equations with Boundary Value Problems
by John Polking, Albert Boggess, and David Arnold.
This page contains download links to the latest Java versions of
pplane. The original
MATLAB versions can be found at:
written as java applets meant to be run in a browser. These are
being discontinued because of security reasons. The apps availalble
here are the replacements.

They are not in the public domain. However, they are being made
available free for use in educational institutions. This offer does not
extend to any application that is made for profit. Users who have such
applications in mind should contact John C. Polking. The Java versions
were written by Joel Castellanos in collaboration with John C. Polking.
