Subject: Octave 0.81 (binaries and src) Now Available

[ Moderator's note: Mr. Johnson later informed me that the files have
  been moved to /pub/Linux/apps/math.  --liw ]

I have uploaded statically linked binaries (including IEEE support) of
Octave version 0.81 to sunsite.unc.edu in /pub/Linux/Incoming.  Unaltered
sources are also there as octave compiles out of the box though, as noted
below, for proper IEEE handling of NaN and Inf you must link with an
altered version of crt0, which has been uploaded as well.

Compiling requires at least GCC 2.5.6, I used GCC 2.5.7 and the 4.5.8 
libraries.  However as the compiled binaries are static they should 
work on older systems without difficulty.

The following contains information on octave and where to send problem
reports.

Title:		Octave
Version:	0.81
Description:	Octave is a high-level language, primarily intended
		for numerical computations.  It provides a convenient
		command line interface very similar to Matlab[tm] for
		solving linear and nonlinear problems numerically, and
		for plotting the results (using gnuplot).
		    Octave can do arithmetic for real and complex
		scalars and matrices, solve sets of nonlinear
		algebraic equations, integrate functions over finite
		and infinite intervals, and integrate systems of
		ordinary differential and differential-algebraic
		equations.
		    The underlying numerical solvers are currently
		standard Fortran ones like Lapack, Linpack, Odepack,
		the Blas, etc., packaged in a library of C++ classes.
Author:		John W. Eaton <[email-masked]>
Maintained-by:	The author.  Version 0.81 binary compiled and uploaded
		by Phil Johnson <[email-masked]>.
Maintained-at:	ftp.che.utexas.edu
Mailing list:	[email-masked] (discussion)
		[email-masked] (bug reports)
Platforms:	Most Unix-like systems that have a working g++/libg++.
		To compile with	IEEE support on Linux systems, get the
		crt0.S (or crt0.o) from ftp.che.utexas.edu in the 
		pub/octave/i486-linux directory.  For graphics, Octave
		also requires gnuplot.

Overview
--------

Octave is a high-level language, primarily intended for numerical
computations.  It provides a convenient command line interface for
solving linear and nonlinear problems numerically.

Octave is free software; you can redistribute it and/or modify it
under the terms of the GNU General Public License as published by the
Free Software Foundation; either version 2, or (at your option) any
later version.

Octave is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
FITNESS FOR A PARTICULAR PURPOSE.  See the file COPYING for more
details.

Availability
------------

The latest released version of Octave is always available via
anonymous ftp from ftp.che.utexas.edu in the directory /pub/octave.
Complete source and binaries for several popular systems are
available.

Installation and Bugs
---------------------

Octave requires approximately 25MB of disk storage to unpack and
install (significantly 	less if you don't compile with debugging
symbols).  In order to build Octave, you will need a current version
of g++, libg++, and GNU make.  Octave is known to compile on the
following systems:

  SPARCstation 2	SunOS 4.1.2
  IBM RS/6000		AIX 3.2.x
  DECstation 5000/240	Ultrix 4.2a
  i486			Linux
  i486			NetBSD (without IEEE floating point support)
  HP 9000/7xx		HP-UX 9.x
  SGI			Irix 4.04
  NeXT			?

As of version 0.80, you must have G++ 2.5.6 or later to compile
Octave.

See the notes in the files INSTALL and INSTALL.OCTAVE for more
specific installation instructions, including directions for
installing Octave from a binary distribution.

The file BUGS contains a recommended procedure for reporting bugs, as
well as a list of known problems.

Binary Distributions
--------------------

Binary copies of Octave are now distributed for several popular Unix
systems.  To save disk space, the complete source code for Octave is
no longer included with the binary distribution, but should be
available in the same place as the binaries.  If not, please contact
[email-masked].

The file INSTALL.OCTAVE contains specific installation instructions,
for installing Octave from a binary distribution.

Implemenation
-------------

Octave is being developed with the Free Software Foundation's make,
bison (a replacement for YACC), flex (a replacement for lex), gcc/g++,
and libg++ on a SPARCstation II and a DECstation 5000/240.  It should
be possible to install it on any machine that runs GCC/G++.  It may
also be possible to install it using other implementations of these
tools, but it will most certainly require much more work.  Do yourself
a favor and get the GNU development tools, either via anonymous ftp
from prep.ai.mit.edu or by writing the Free Software Foundation, 675
Mass Ave, Cambridge, MA 02139, USA.

The underlying numerical solvers are currently standard Fortran ones
like Lapack, Linpack, Odepack, the Blas, etc., packaged in a library
of C++ classes (see the files in the libcruft and liboctave
subdirectories).  If possible, the Fortran subroutines are compiled
with the system's Fortran compiler, and called directly from the C++
functions.  If that's not possible, they are translated with f2c and
compiled with a C compiler.  Better performance is usually achieved if
the intermediate translation to C is avoided.

The library of C++ classes may also be useful by itself.
