Naturally because it's on "simplecv.tumblr.com" this is pretty biased.<p>But some glaring omissions<p>1) You can compile Matlab to C++ code which is much faster.<p>2) With respect to Portability there is the glaring omission of Octave (nor to mention there is MATLAB for unix systems). (I guess that also counts for the price issue). I'm not a MATLAB guru, but in the couple of times I've used it, it seems like MATLAB minus the handy dandy documentation and IDE.<p>3) Debugging in Matlab's ID is so easy a 5 year old can do it. The variables are all there; you can double click on any to see their contents. Debugging in a shell in my experience is a much bigger PITA.<p>4) I didn't look at their documentation, but I honest really doubt it's better then MATLAB's. I've never seen documentation so well written in an open source project.
