octave - A high-level interactive programming language for numerical computations.


octave [options]... [file]


Octave is a high-level interactive scientific programming language. It has a powerful mathematics-oriented syntax for solving problems numerically, as well as built-in 2-D/3-D plotting and visualization tools. Octave provides an integrated development environment in either graphical or command-line form. Programs may also be run in batch mode to process data without interaction.


A list of the most useful command-line options for octave is available by running the following command from the shell.

octave --help


The primary documentation for Octave is written using Texinfo, the GNU documentation system, which allows the same source files to be used to produce online and printed versions of the manual.

You can read the built-in copy of the Octave documentation by issuing the following command from within octave.

octave:1> doc

The Info files may also be read with a stand-alone program such as info or xinfo. HTML, Postscript, or PDF versions of the documentation are installed on many systems as well. The latest version of the documentation is available at">

Upon startup Octave looks for four initialization files. Each file may contain any number of valid Octave commands.

Site-wide initialization file which changes options for all users. octave-home is the directory where Octave was installed such as /usr/local.

User’s personal initialization file.
