XPP

XPP is a tool for solving :

- differential equations
- difference equations
- delay equations
- functional equations
- boundary value problems
- 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.

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.

XPP has the capabilities for handling up to 590 differential equations.
