GNU Octave 6.1.0
When I left university and did not have access to MATLAB anymore, I spent many a nights hacking away at GNU Octave. I have fond memories of Octave.<p>I thought Octave will be a valuable skill when I enter the industry but I could not have been more wrong. Does anyone still use Octave? Is it worth learning?<p>What tools or languages would you recommend as alternatives to someone graduating from university today?
