GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. GNU Octave is normally used through its interactive interface (CLI and GUI), but it can also be used to write non-interactive programs. The GNU Octave language is quite similar to Matlab so that most programs are easily portable.

The latest released version of Octave is always available from and many mirror sites around the world. You may also find links to binary distributions at The current development sources may be found under the Source Code tab on Savannah.


Octave requires approximately 475 MB of disk storage to unpack and compile from source (significantly more, 3.8 GB, if you compile with debugging symbols). Once installed, Octave requires approximately 75 MB of disk space (again, considerably more, 415 MB, if you don't build shared libraries or the binaries and libraries include debugging symbols).

To compile Octave, you will need a recent version of:

Octave's Makefiles use features of GNU Make that are not present in other versions of make. If you use f2c, you will need a script like fort77 that works like a normal Fortran compiler by combining f2c with your C compiler in a single script.

See the notes in the file INSTALL.OCTAVE of the Octave source distribution for more detailed installation instructions.

Bugs and Patches

The file BUGS (or doc/interpreter/bugs.txi) explains the recommended procedure for reporting bugs on the bug tracker or contributing patches; online documentation is also available here.


  • Octave's manual is a comprehensive user guide covering introductive and more advanced topics.
  • Octave's wiki is a user community page, covering various topics and answering FAQ.
  • Octave's Doxygen documentation explains the C++ class libraries.

Partially, the up-to-dateness of the documentation is lagging a bit behind the development of the software. If you notice omissions or inconsistencies, please report them at our bug tracker. Specific suggestions for ways to improve Octave and its documentation are always welcome. Reports with patches are even more welcome.
