Subject: [comp.lang.c++] The C++ Matrix class
Date: 10 Jul 1993 11:46:52 GMT

Archive-name: auto/comp.lang.c++/The-C-Matrix-class

I have updated The C++ Matrix class so that it will compile without complaint
with version 2.4.5 of the Gnu C++ compiler `g++'.  It still compiles with
version 2.3.3 of the Gnu compiler and version 2.1 of Sun's `cfront' compiler
`CC'.  It has been tested on Sun4 computers running SunOs 4.1.1, Sun4m
computers running SunOs 5.2, NeXT computers running Mach 3.0, Silicon Graphics
computers running IRIX 4.0.5 and 386 computers running Linux 0.99.10.  Please
send me email if you have trouble installing on these or any other platforms.

The C++ Matrix class is available via anonymous ftp from `ftp.cs.ucla.edu'.
Get the compressed tarfile `pub/Matrix.tar.Z'.  Uncompress `Matrix.tar.Z'.
Extract the `Matrix' directory from `Matrix.tar'.  Then go to the `Matrix'
directory and type `make'.  Now print and read the paper in `Matrix.dvi'.

In order to demonstrate an application of the \verb"Matrix" class,
it was used to implement the backward error propagation algorithm
for multi-layer, feed-forward artificial neural networks.

Enjoy, Bob Tisdale (edwin@cs.ucla.edu)

      If you have trouble, verify that the `SYS5' variable
      in the `Matrix/src/genclass' shell script contains
      the path to the System V version of the `m4' macro
      pre-processor.
      The `fig2dev' program is part of the `transfig' package
      available via anonymous ftp from `ftp.cs.cornell.edu'.
      Get `pub/transfig/transfig.tar.Z'.
      The EPIC style file is available via anonymous ftp from
      `ymir.claremont.edu'. Get `tex/inputs/latex-contrib/epic.sty'.
      File `pub/Matrix.sun.tar.Z' includes all the files created by
      `make' on UCLA CSD Sun4 computers.  It may be useful to Sun
      computer users or those who just want to print the documentation.
