Octave binary packages are provided from OSS repository of all actual openSUSE versions. Octave can be installed with the help of YaST or zypper command
zypper install octave


  zypper in octave
It is recommended to additionally install the development files. They are required, for installing [[#Octave Forge packages|Octave Forge]] packages outside openSUSE's OSS repository or to create applications using Octave.


If you want to use latest stable version of Octave, you can use Science repository.
zypper install octave-devel


  zypper addrepo http://download.opensuse.org/repositories/science/<openSUSE version>/ Science
==== The science repository ====
 
If you want to use '''latest stable version of Octave''', you can obtain the binary packages via [https://software.opensuse.org/download.html?project=science&package=octave One Click Install] from the science repository.
 
To add the science repository manually, use the zypper commands (<code><openSUSE_version></code> is for example <code>openSUSE_Leap_15.1</code>):
 
  zypper addrepo http://download.opensuse.org/repositories/science/<openSUSE_version>/science.repo
  zypper refresh
  zypper refresh
zypper install --from Science octave


There <openSUSE verion> is your version of openSUSE, for example {{codeline|openSUSE_13.1}}
And to install Octave from the science repository type:
