We're actually pretty feature complete wrt Matlab. The biggest things that are missing are the GUI, classdef OOP, and a JIT compiler. All of these currently have very lively and active development. Hopefully our next Octave release will seem less archaic to you. The language itself is very feature complete, however. Our main current goal has been for you to be able to grab your Matlab code and run it without modification in GNU Octave. For 99.9% of the lines of code in your code (assuming you don't use classdef), this works. The problem is that you might not always want to modify the remaining 0.1% lines of code to make them run in GNU Octave.
