I've always wanted to try Numpy for this purpose, but I get exposed to so much MATLAB code in research papers for DSP that it hardly seems worthwhile.
Furthermore, I've built an entire Objective-C math framework (https://bitbucket.org/liscio/smugmath) that operates very similarly to MATLAB (i.e. vector-oriented) and allows me to easily translate DSP algorithms found in research papers over to shipping products (http://capoapp.com, http://fuzzmeasure.com).
