StdMap

Area-preserving mappings model the dynamics of such systems as forced pendulums and the dynamics of stars in galacties and the flow of magnetic field lines. StdMap displays the orbits of 13 different such mappings which exhibit chaotic and regular dynamics. With the program you can find periodic orbits, stable manifolds and invariant circles/cantori, and iterate arbitrary curves.

What is new in this release:

• Changed the label for the Suris Map parameter from "k" to "a"
• Reorganized the Find menu to make it more logical
• Fixed a bug in Curve drawing where CycleColor was not respected
• Fixed a potential crash if iterate a box was done too long (probably physically impossible to hit the spacebar that much!)
• Added warning to user if p & q are not selected to be coprime (Orbit finding)
• Fixed the Help anchors to work with 10.5
• Fixed a cursor setting bug if a help window was open
• Fixed a bug in the EditOrbitList dialog for setting the y-value
• Disabled Print Menu items if Plot is not front window. Removed "sheets" for Print Dialogs due to a bug in 10.5
