Pre-compiled binaries
Binary packages for Octave are provided by all versions of openSUSE. These are the most well-tested binaries available and should work best for most users.
zypper in octave
If you want to use install latest stable version of Octave and Octave Forge packages, you can use Science repository.
zypper ar http://download.opensuse.org/repositories/science/<openSUSE version>/ Science zypper ref zypper in octave
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.
