The best feature of freemat it's that you can use both MATLAB AND OCTAVE at once! It has many features like GUI interface, plotting etc which makes user experience great in terms of software development process. I had no issues with this tool so far but if there are any problems then please let me know immediately because we will try to solve them ASAP. Since I am working mostly within my field (Electrical Engineering) i think its good fit since most engineers uses matlab or octave frequentlyโฆ
