Notice that octave has packages as well. In particular, it has the "signal" package which is a somewhat limited clone of the corresponding matlab toolbox. Depending on your specific needs it may be alright for your application. In my experience the "core" parts of packages are well-replicated, but the user-interfaces are somewhat lacking in the octave side. Since I use octave mostly non-interactively, I do not really care about that.
