If you want to use install latest stable version of Octave and Octave Forge packages, you can use Science repository.

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

Octave Forge

Octave-Forge binary packages are provided by 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 is 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:

  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

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.
