| Numerical Analysis
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.
Current Version: 1.3
License Type: Free
Source Code Availability:
Available Binary Packages:
- Debian Package: No
- RedHat RPM Package: No
- Other Packages: No
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.
