Installation[edit]

Octave binary packages are provided from the OSS repository of all recent openSUSE versions. Octave can be installed using One Click Install, YaST, or the zypper command:

zypper install octave

The science repository[edit]

If you want to use latest stable version of Octave, you can obtain the binary packages via One Click Install from the science repository.

To add the science repository manually, use the zypper commands (<openSUSE_version> is for example openSUSE_Leap_42.3):

zypper addrepo http://download.opensuse.org/repositories/science/<openSUSE_version>/science.repo
zypper refresh

And to install Octave from the science repository type:

zypper install --from science octave

Octave Forge packages[edit]

Octave-Forge binary packages are provided from the OSS and science repository. You can list all available packages by the zypper command:

zypper search octave-forge*

Linear algebra libraries[edit]

openSUSE uses reference BLAS and LAPACK implementations by default, but ATLAS or OpenBLAS are usually much faster. You can switch it by update-alternatives mechanism:

/usr/sbin/update-alternatives --config libblas.so.3
/usr/sbin/update-alternatives --config liblapack.so.3

Example:

There are 4 choices for the alternative libblas.so.3 (providing /usr/lib64/libblas.so.3).

  Selection    Path                             Priority   Status
------------------------------------------------------------
* 0            /usr/lib64/libblas.so.3.4.2       50        auto mode
  1            /usr/lib64/atlas/libsatlas.so.3   20        manual mode
  2            /usr/lib64/atlas/libtatlas.so.3   20        manual mode
  3            /usr/lib64/libblas.so.3.4.2       50        manual mode
  4            /usr/lib64/libopenblasp.so.0      20        manual mode

See linear algebra libraries page at openSUSE wiki for more information.

Image export and import[edit]

GraphicsMagick++ library from openSUSE repositories was compiled with quantum depth 16 which limits reading and writing images to 16 bit. See more details on GraphicsMagick wiki page.

Bug reporting[edit]

You can report openSUSE specific bugs by pressing "Report Bug" button on OBS Octave page (openSUSE bugzilla account required).
