Features of traj
traj was originaly designed for use in an ordinary differential equations
(ODEs) classroom. It was designed to be a tool for the visualization of the solutions
to ODEs. The primary features include the following:
- The trajectories can be viewed in three
dimensions,
- The view is interactive allowing you to
rotate and zoom the view,
- Multiple trajectories can be viewed at once,
- The view is in the phase space but can include the time axis,
- Trajectories can be edited interactively,
- Trajectories can be generated by providing the equations for a system of
ODEs using the following approximation techniques:
- Four/Five Runge-Kutta-Fehlberg (Variable Time Step - this is the default integrator),
- Fourth order Runge-Kutta,
- Euler Scheme,
- Trajectories can be read from a data file in text format,
- The axes used for the phase space can be changed interactively,
- The software is distributed under an open and
free license, the GNU
Public License so it can be copied freely, used in any way you like,
and you can make any change that you lik to the software,
- The documentation is written in LaTeX,
and the source files are made available under the GNU Public Documentation
license so you are free to make any changes and distribute your changes,
