There was a little bit more information about that above. I'm a professional and my initial cost was around $2k and my yearly cost is around $400. I don't have to pay the yearly, but I like the updates and I like getting a response when something breaks and I'm on a tight deadline. I can't stress enough that what you buy with MATLAB is license coverage. Octave and Julia hook into many of the exact same libraries, but they have not negotiated a commercial license for things like linear system solvers. That means that distributed binaries may be subject to things like the GPL. If that's what you want, great. I like the GPL for a certain kind of software delivered to a certain kind of clientele. However, it's a nonstarter for most of my clients, so they buy MATLAB.
