You missed significant language here -- R (http://www.r-project.org/ http://www.r-project.org/). Its array model is way better than Matlab, has all functional goodies on board, excellent expressiveness, can flawlessly represent real data (there are built-in missing values, ordered and unordered categorical variables, data commenting, arbitrary metadata, even a "spreadsheet" type) and absolutely huge library (biased into data science, but it features linear algebra, optimization and DEs). It is also pretty fast, especially because it is easy to write C/Fortran accelerators so they are present behind many library functions. And in contrast to Julia/Cobra it exists for a while, so way more bugs/flaws is already fixed/understood.
