XPPAUT 5.85

XPPAUT 5.85 software available at: http://www.math.pitt.edu/~bard/xpp/xpp.html

XPP (XPPAUT is another name; I will use the two interchangeably) is a tool for solving

  • Differential equations
  • Difference equations
  • Delay equations
  • Functional equations
  • Boundary value problems
  • Stochastic equations

It is now available as a program running under X11 and Windows.

The code brings together a number of useful algorithms and is extremely portable. All the graphics and interface are written completely in Xlib which explains the somewhat idiosyncratic and primitive widgets interface.

XPP contains the code for the popular bifurcation program, AUTO . Thus, you can switch back and forth between XPP and AUTO, using the values of one program in the other and vice-versa. I have put a ``friendly'' face on AUTO as well. You do not need to know much about it to play around with it.
