Eaton + +Last updated: Mon Feb 5 13:27:40 1996 + +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.wisc.edu in the directory /pub/octave. +Complete source and binaries for several popular systems are +available. + +Installation and Bugs +--------------------- + +Octave requires approximately 50MB 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. + +YOU MUST HAVE GNU MAKE TO COMPILE OCTAVE. Octave's Makefiles use +features of GNU Make that are not present in other versions of Make. +GNU Make is very portable and easy to install. + +As of version 1.1.x, you must have G++ 2.6.2 or later to compile +Octave. In some cases, you may also need to install a patch for g++ +that is distributed with Octave in order to successfully 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 and possible fixes. + +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 +not included in the binary distributions, but should be available in +the same place as the binaries. If not, please contact +bug-octave@bevo.che.wisc.edu. + +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, +59 Temple Place - Suite 330, Boston, MA 02111-1307, 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. + +-- +John W.
