Octave is a computer program for performing numerical computations which is mostly compatible with MATLAB . It is part of the GNU Project. It is free software under the terms of the GNU General Public License.

OpenMatrix Language (OML) is described as 'The OpenMatrix Language provides all scientists, technologists, engineers, & mathematicians (i.e., people in STEM fields) with open access to a powerful matrix-based computational engine' and is an app in the education & reference category. There are nine alternatives to OpenMatrix Language (OML) for a variety of platforms, including Windows, Linux, Mac, Flatpak and Flathub apps. The best OpenMatrix Language (OML) alternative is GNU Octave, which is both free and Open Source. Other great apps like OpenMatrix Language (OML) are MATLAB, Scilab, Nelson and Freemat.
