Octave packages

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 in octave

If you want to use latest stable version of Octave, you can use Science repository.

zypper addrepo http://download.opensuse.org/repositories/science/<openSUSE version>/ Science
zypper refresh
zypper install --from Science octave

There <openSUSE verion> is your version of openSUSE, for example openSUSE_13.1

Octave Forge packages

Octave-Forge binary packages are provided from Science repository. You can list all available packages by command

zypper se octave-forge

Linear algebra libraries

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

Image export and import

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

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