"Review on GNU octave"

What do you like best about GNU Octave?

The best part about octave is it is open source and anyone (even atudent) can use it. The programming language is very easy and proves to be a great alternative if you don't have Matlab in-hand. Review collected by and hosted on G2.com.

What do you dislike about GNU Octave?

Nothing in particular but regular update is required for removal of bugs Review collected by and hosted on G2.com.

Recommendations to others considering GNU Octave:

Easy to use open source software for someone who works in technical area and need to undergo complex calculation while performing simulation or modelling. Review collected by and hosted on G2.com.

What problems is GNU Octave solving and how is that benefiting you?

I solved the complex equations while working as a undergraduate researcher and the ease of writing code made it a perfect solver for solving my simultaneous complex equations. Review collected by and hosted on G2.com.

"Octave Review by Hassan Charafeddine"

What do you like best about GNU Octave?

It is almost the same syntax at Matlab can do 90% of the work and more, got improved a lot over the time Review collected by and hosted on G2.com.

What do you dislike about GNU Octave?

Not much, but the plots can be improved, the editor and UI can improve a bit, but overall satisfied Review collected by and hosted on G2.com.

"Great Open Source Mathematical Software"

What do you like best about GNU Octave?

Variety of tasks and Functions and documentation. Review collected by and hosted on G2.com.

What do you dislike about GNU Octave?

Octave does not integrate CAD and PLM well. Review collected by and hosted on G2.com.

Recommendations to others considering GNU Octave:

Octave is a great alternative to MATLAB and the pace with it is growing and the community behind it might be if not greater but equal to MATLAB. But since MATLAB is quite prevalent in the industry, it is hard to beat. With the huge community of developers backing up this project and more advertising Octave is surely a great product. However, the only problem I have seen in it is the integration of CAD with PLM software. Sometimes it fails to register the commands and skips them when integrating it but sometimes does the job. Review collected by and hosted on G2.com.

What problems is GNU Octave solving and how is that benefiting you?

I am solving day to day computational and graphical problems with octave. The Realization is that it requires much less space than MATLAB and is open to everyone to use.

By using it for Computer Aided Engineering practice, it makes me realize that, how more often people will go to GNU Octave for the same purpose. When I use it for statistical analysis it performs the tasks smoothly. Like I have used it for ANOVA and other regression models that they run just fine. I haven't modeled anything related to statistical learning where huge computation is required, but I am sure it will have such capabilities to run such models pretty efficiently. I have also done some Fluid mechanics and manufacturing process simulation in octave and the software makes it look easy enough. Review collected by and hosted on G2.com.

"A Comman Man's MATLAB"

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.

"The most intuitive mathematically optimized language just doesnt quite hit it"

What do you like best about GNU Octave?

Linear algebra is a complete breeze with the language's vanilla syntax. Compared to more modernly popular languages used for Data Science such as Python , GNU Octave allows you to run tensor algebra operations using only built-in functions without having to import any 3rd party packages or modules. Despite Numpy being the standard and most commonly used library for linear algebra, I would honestly say that I still believe that even Numpy could learn a thing or two about the ease of use of Octave's mathematical syntaxes. The fact that one could implement complex matrix-vector operations in GNU Octave with mostly only built-in operators and rarely having to call functions proves just how well-optimized the language is for mathematical purposes. Review collected by and hosted on G2.com.

What do you dislike about GNU Octave?

Despite the language's well-optimized math functions, everything else just feels a bit too clunky and complicated for a high-level language. For instance, building functions and calling those functions Review collected by and hosted on G2.com.

Recommendations to others considering GNU Octave:

Use it primarily for practicing building machine learning models from scratch to test your knowledge of the underlying algorithms and mathematical concepts but stick to Python along with frameworks such as Tensorflow 2.0, Pytorch, or Sci-kit learn when it comes to building bigger and more complex models. If you've been using Python or R for most of your previous projects, I'd say stick with those even for practicing and prototyping as learning GNU Octave syntax, though relatively easy to pick-up, might lead to unwanted syntax mixing when switching between the languages. Review collected by and hosted on G2.com.

What problems is GNU Octave solving and how is that benefiting you?

Coding machine learning programs from scratch. Octave's inclination towards linear algebra allows you to create the building block functions of machine learning applications in only few lines of code. Review collected by and hosted on G2.com.
