Engineer Small-Business (50 or fewer emp.) 1/9/2021 "A Comman Man's MATLAB" 4.5/5 What do you like best about GNU Octave? This is a perfect, free and open source software which can be used as an alternative to MATLAB as the syntax and the functions are similar. The documentation similar to MATLAB can be used for this software as well. You can do almost all the things that MATLAB can do except some missing libraries. I really like using Octave for some machine learning problems as the variables that are defined are matrix based and it is easier to have matrix operation in ML problems. The GUI is similar to MATLAB and there it feels like we are just using MATLAB. Best thing about GNU octave is that we can code it online as there are many websites available Review collected by and hosted on G2.com. What do you dislike about GNU Octave? GNU Octave does not have all the functionalities that MATLAB has and therefore sometimes we need to write our modules by ourselves which is a big downside. This occurs when we are solving some complex problem using Octave. Also, there are no written modules/functions/libraries available for ML programs unlike python and thus it is difficult to code neural Networks in it as the code gets lengthy. Review collected by and hosted on G2.com. Recommendations to others considering GNU Octave: You can download their offline version from the website and it has a GUI which is similar to MATLAB Review collected by and hosted on G2.com. What problems is GNU Octave solving and how is that benefiting you? I am doing a MOOC course on ML which is taken by Andrew NG, a visiting professor in ML. He has designed the course such that the programming assignment are to be worked upon in GNU Octave. I have completed all the assignments in Octave. I am also working on some data analysis using OCTAVE as it is easier Review collected by and hosted on G2.com. Show More Current UserValidated ReviewerIncentivizedSource: G2 invite SU Samantha U.
