xppaut – Phase Plane Plus Auto: Solves many kinds of equations

XPPAUT is a tool for solving

  • differential equations,

  • difference equations,

  • delay equations,

  • functional equations,

  • boundary value problems, and

  • stochastic equations.

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.
