GNU Octave
Octave seems great since it’s open and let’s you run Matlab scripts.<p>A bit offf topic, but is Matlab relevant still? I’ve heard it’s still in use a lot, but what’s the benefit of going with a walled off proprietary $$$ tool when you can use something like this? Python and R also seem like they’re growing so much and are very open.<p>I just remember taking a class on Matlab and being pretty disappointed in it with how closed it felt. Will totally check out octave tho!
