Octave version 2.0 is now available for ftp from ftp.che.wisc.edu in the directory /pub/octave. Diffs from the previous release are not available because they would be quite large.
This is a major new release and includes many new features. User-visible changes since the last release are listed in the file NEWS, which is included in the distribution and available from ftp.che.wisc.edu in the file /pub/octave/NEWS. The ChangeLog files in the source distribution contain a more detailed record of changes made since the last release.
Most bugs reported since the release of version 1.1.1 have been fixed. You can help make Octave more reliable by reporting any bugs you find to firstname.lastname@example.org.
What is Octave? ---------------
Octave is a high-level interactive language, primarily intended for numerical computations that is mostly compatible with Matlab.
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.
Octave uses the GNU readline library to handle reading and editing input. By default, the line editing commands are similar to the cursor movement commands used by GNU Emacs, and a vi-style line editing interface is also available. At the end of each session, the command history is saved, so that commands entered during previous sessions are not lost.
The Octave distribution includes a 200+ page Texinfo manual. Access to the complete text of the manual is available via the help command at the Octave prompt.
Two and three dimensional plotting is fully supported using gnuplot.
The underlying numerical solvers are currently standard Fortran ones like Lapack, Odepack, Dassl, the Blas, etc., packaged in a library of C++ classes. 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, you can still compile Octave if you have the free Fortran to C translator f2c.
Octave is also 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.

By ordering your GNU software from the FSF, you help us continue to develop more free software. Media revenues are our primary source of support. Donations to FSF are deductible on US tax returns.
The above software will soon be at these ftp sites as well. Please try them before prep.ai.mit.edu as prep is very busy!
