Octave is quite nice for linear algebra and it does have the big
advantage of being free. The problem is that I am doing image processing
which requires heavy algorithms on large matrices and proper support for
graphics (2D and 3D). Regratably octave is not up to the task.
The contour function is way to slow and unstable and its image display
support far from being flexible enough. Its about at the stage of matlab
5 (which is quite impressive for a free program).
Another nice option is the pdl extension of perl. Its fast and quite
usable. The problem with it is that its not command line drive but run
from the shell (although there is a simple command line, but it could
use history and completion functionality). Also the syntax is very
different from matlab, so porting isn't really possible.
Another thing that I have to take into account is that I have to
collaborate with colleagues in uni so I don't have much choice.
