The recommended way for installing Octave and Octave-Forge packages on GNU/Linux systems
[https://www.gnu.org/software/octave/ 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. The program is named after [https://en.wikipedia.org/wiki/Octave_Levenspiel Octave Levenspiel], a former professor of the principal author. GNU Octave is normally used through its interactive interface ([https://en.wikipedia.org/wiki/Command-line_interface CLI] and [https://en.wikipedia.org/wiki/Graphical_user_interface GUI]), but it can also be used to write non-interactive programs. The project was conceived around 1988 and at first it was intended to be a companion to a chemical reactor design course. The GNU Octave language is largely compatible to [https://en.wikipedia.org/wiki/MATLAB Matlab] so that most programs are easily portable.

The package can be obtained from the Software Center but the Octave package is old (3.2).  The most current stable version is available through a Personal Package Archive (PPA).  You will need to add the PPA to you system. Execute the following in a terminal:


    sudo apt-add-repository ppa:octave/stable
== 📦 [[:Category:Packages|Packages]] ==
    sudo apt-get update


If you need more information on adding a repository, visit [https://launchpad.net/~octave/+archive/stable GNU Octave Stable Releases] PPA. You can now install from the Software Center or a terminal.

* [https://savannah.gnu.org/bugs/?group=octave Bug Tracker]
The packages can be installed using the yum command, they are:
* [https://savannah.gnu.org/task/?group=octave Task Tracker]
 
* [https://savannah.gnu.org/patch/?group=octave Patch Tracker]
*octave
* [https://savannah.gnu.org/hg/?group=octave Development Repository]
*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.

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. The program is named after Octave Levenspiel, a former professor of the principal author. GNU Octave is normally used through its interactive interface (CLI and GUI), but it can also be used to write non-interactive programs. The project was conceived around 1988 and at first it was intended to be a companion to a chemical reactor design course. The GNU Octave language is largely compatible to Matlab so that most programs are easily portable. In addition, functions known from the C standard library and from UNIX system calls and functions are supported. C/C++ and Fortran code can be called from Octave by creating Oct-Files, or using Matlab compatible Mex-Files.
