xppaut.2.71.README Feb 1997 The archive: xppaut.2.71.NIHS.bd.tar.gz Built using: gcc-2.7.2.1.f.1 (with g77/f2c support, for m68k and i386 binaries), cc-2.5.8 (with f2c support, hppa and sparc binaries) libX11.a (Xnext X11R6 library). OVERVIEW XPP is a tool for solving differential equations, difference equations, delay equations, functional equations, boundary value problems, and stochastic equations. It evolved from a chapter written by John Rinzel and Bard Ermentrout on the qualitative theory of nerve membranes and eventually became a commercial product for MSDOS computers called PHASEPLANE. It is now available as a program running under X11 and UNIX. 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 somwhat 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. There is a "friendluy" face on AUTO as well. You do not need to know much about it to play around with it. INSTALLATION A simple Installer.app package, to be placed anywhere, but /usr/local is a good place to start.
