Planar Maps and DE's

These Macintosh programs were written by Ben Hinkle, as an undergraduate at Cornell around 1994, under the direction of John Hubbard. This webpage was posted by Suzanne Lynch Hruska. Send email to: shruska@msm.umr.edu with comments/questions on the website.

PlanarIterations.fat.sit for 2D maps, good for drawing stable/unstable manifolds, and finding periodic points, etc.
PlanarSystems.fat.sit for exploring 2D ODE's.
Examples from Planar Iterations are some samples of saved work on the henon map.

There is a help/tutorial included with the software.

To export your pictures, go to the File menu and choose Export (you get to select PICT or EPS format).

Here's an example of what Planar Iterations looks like:
