> a company that is built around Octave How many of those are there? I give talks pretty frequently where I start by asking people in the audience what tools they regularly use for technical computing, and I'm legitimately surprised the few times anyone says they use Octave for things beyond classroom-level work. No offense intended to its developers, but Octave as a project seems like misdirected effort to me. Matlab the language isn't the most useful thing to try to emulate, Matlab the environment and tool set for getting non-software engineering jobs done is why people use it. For example, an increasing portion of the people who still use Matlab do so largely because of Simulink, for which there isn't a comparably effective open source alternative yet (you can sometimes use Modelica but there's less overlap in users than you'd think).
