The recommended way for installing Octave and Octave-Forge packages on GNU/Linux systems
[http://www.octave.org 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.

If you want to be able to build packages from Octave Forge, you will want liboctave-dev package:
 
    sudo apt-get install liboctave-dev
 
If you want Octave debugging symbols, use the following:
 
    sudo apt-get install octave-dbg
=Fedora=
The packages can be installed using the yum command, they are:
 
*octave
*octave-devel
*octave-forge
 
{{Codeline|octave-forge}} is recommended to all users, as it provides many extra functions. {{Codeline|octave-devel}} contains the octave headers and {{Path|mkoctfile}} script and is really only needed by users who are developing code that is to be dynamically linked to octave. {{Codeline|octave}} and {{Codeline|octave-forge}} can be installed with the command:
 
    # yum install octave-forge
 
By default, yum will most likely install blas and lapack as your matrix math libraries, but ATLAS is usually much faster. If you want to install atlas with octave, use the command
 
    # yum install octave-forge atlas
 
Note that if you are using an i386-compatible processor the base atlas package is not optimized for newer hardware. If you have newer hardware, you can get even better performance with the atlas-3dnow (AMD K6 processors), atlas-sse (Pentium III or newer), or atlas-sse2 (Pentium 4 or newer).
 
=Gentoo=
Octave is available through Gentoo's package management system, Portage:
 
    # emerge sync
    # emerge octave
    # emerge octave-forge (optional)
 
=Red Hat Enterprise=
 
Octave is available for Red Hat Enterprise Linux distributions through the [https://fedoraproject.org/wiki/EPEL EPEL] repository. This section applies to CentOS, Scientific Linux, and other Red Hat Enterprise rebuild distributions as well.
 
First, follow [https://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F these instructions] to set up your system to install packages from EPEL. For example,
 
    # wget <nowiki>http://url/to/latest/epel-release-6-7.noarch.rpm</nowiki>
    # yum localinstall epel-release-6-7.noarch.rpm
 
Once the EPEL repository has been enabled, you can follow the rest of the [[#Fedora|instructions for Fedora]] to install Octave using yum.
 
Note that EPEL intentionally does not follow new releases as closely as other distributions. Consequently, the version of Octave provided by EPEL may be several months or years out of date. There are plans for the Octave maintainers to provide support and binary RPMs for enterprise GNU/Linux distributions, contact the [mailto:maintainers@octave.org maintainers mailing list] for more information.
 
=Red Hat=
 
GNU Octave is included with Red Hat. If you are still using an old version of Red Hat and want a newer version of GNU Octave, your best options are to consider updating your distribution to a recent Fedora release or compile octave from source.
 
Note that RH 7.x distributions (as well as Red Hat Enterprise Linux 2.1) have included an old version of GCC (pre 3.x). It is known that GCC 2.96 (included in RH7.3) can compile GNU Octave (as of version 2.1.57), but the resulting binary will be bad. Red Hat made available RPMs for GCC 3.1-5 through http://rhn.redhat.com (those RPMs may be available on other RPM repositories).
 
=SUSE Linux Enterprise and openSUSE=
Octave 3.6.2 is included in the science repository with SLE 11 SP2 and openSUSE 11.4, 12.1, 12.2
 
[http://download.opensuse.org/repositories/science/ OBS science]
 
For example, for openSUSE 12.2 you would do:
 
    # zypper ar http://download.opensuse.org/repositories/science/openSUSE_12.2/ science
    # zypper refresh
    # zypper install octave octave-devel
 
for other versions change the version number in the first command accordingly.
 
2012-08-21: arpack-ng and SuiteSparse 4.0 bindings which were broken before are again functional, if you have a previous version of the rpm's installed consider to update them.
 
[[Category:GNULinux]]
 
=Arch Linux=
 
Updated Octave's version is in the extra repository. It can be installed by typing:
 
    # pacman -S octave
