XTC XTC stands for space-time continuum and is a series of numerical routines as well as an interface for solving evolution equations in one spatial dimension that involve one,two, or four spatial derivatives. The program is able to handle a variety of integral equations as well as diffusion-type PDEs. One of the most useful parts of XTC is the ability to solve for homogeneous equilibria and then do a ``Turing'' stability analysis on the resulting rest state. The ability of the program to do this is somewhat restricted but it works on most systems that have convolution kernels, biharmonics and diffusion terms. The graphics available for 3D includes surface drawing with hidden lines, color coding, grey-scales, and contours. Two-dimensional plots are possible as well such as a variable versus time or space at different points and phase-space plots. Postscript support is expected or perhaps even available. The interface of XTC is very similar to the author's another program XPP-Aut.

Home Site: ftp://ftp.math.pitt.edu/pub/bardware/ (xtc-*) Source Code Availability: Yes Available Binary Packages: Debian Package:   No RedHat RPM Package:   No Other Packages:   No Targeted Platforms: The interface is written in XLIB and so it is completely portable. Much of this code was developed using GCC under MSDOS and DesqView X. It has also been compiled and run on a Sparc 2, an HP 730, and a NeXT under X and under LINUX on a 486.
