Description
Newer Octave is an open source alternative to MATLAB. It is typically less performant than MATLAB due to its lack of a just-in-time compiler, but it requires no licensing. It has fewer toolboxes / less functionality available than MATLAB, but is overall much simpler to set up and is great for back-of-the-napkin linear algebra calculations.
Self-Service Version Installation/Updates
Specific versions of Octave can be installed by using Conda on your Cortex VM. To do so, first search conda-forge to see what versions of Octave are available:
| Code Block |
|---|
(base) -bash-4.2$ conda search -c conda-forge octave Loading channels: done # Name Version Build Channel octave 4.2.1 blas_openblas_0 conda-forge octave 4.2.1 blas_openblas_1 conda-forge octave 4.2.1 blas_openblas_2 conda-forge octave 4.2.1 blas_openblas_3 conda-forge octave 4.2.1 blas_openblas_4 conda-forge octave 4.2.1 blas_openblas_5 conda-forge octave 4.2.1 blas_openblas_6 conda-forge octave 4.2.1 blas_openblas_7 conda-forge octave 4.2.1 h5127272_11 conda-forge octave 4.2.1 h675bd89_15 conda-forge octave 4.2.1 h6b19570_14 conda-forge octave 4.2.1 h7337af8_13 conda-forge octave 4.2.1 hb4c947d_12 conda-forge octave 4.2.1 hf6200dd_15 conda-forge |
When you have found the version that you want, create a new conda environment with that version using the following syntax:
| Code Block |
|---|
(base) -bash-4.2$ conda create -n octave -c conda-forge octave=4.2.1 |
To use the version you want, you can activate your conda environment with the following syntax:
| Code Block |
|---|
(base) -bash-4.2$ conda activate octave
(octave) -bash-4.2$ octave -v
