- From Octave’s web page:
GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.
Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave’s own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.
Simply load the latest version of Octave.
module load octave octave
It is best to pick a version of octave and stick with it. Do
spider octave and use the whole name:
module load octave/4.4.1-qt-python2
To run octave with the GUI, run it with:
Before installing packages you should create a file
~/.octaverc with the
package_dir = ['/scratch/work/',getenv('USER'),'/octave']; eval (["pkg prefix ",package_dir, ";"]); setenv("CXX","g++ -std=gnu++11") setenv("DL_LD","g++ -std=gnu++11") setenv("LD_CXX","g++ -std=gnu++11") setenv("CC","gcc") setenv("F77","gfortran")
This sets up
/scratch/work/$USER/octave to be your Octave package directory
gcc to be your compiler. By setting Octave package directory to
your work directory you won’t run into any quota issues.
After this you should load
texinfo-modules. This gives you an
up-to-date compiler and tools that Octave uses for its documentation:
module load gcc module load texinfo
Now you can install packages in octave with e.g.:
pkg install -forge -local io
After this you can unload the
module unload gcc module unload texinfo
