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
It is recommended to additionally install the development files. They are required, for installing Octave Forge packages outside openSUSE's OSS repository or to create applications using Octave.
zypper install octave-devel
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_15.1):
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).
