Why/when should I prefer MATLAB over Octave?

Question

In our shoestring operation we need to prototype algorithms in some higher-level language before committing to a C implementation on embedded hardware.

So far we hav

There's a good WikiBook on MATLAB with a list of differences between MATLAB and Octave.

In my experience, core MATLAB is well ported to Octave, but the toolboxes have varying levels of compatibility, so your decision depends on what exactly you are trying to code.

Also, as others have pointed out, much of what you pay for with MATLAB is the slick interface and debugging/profiling tools. Experienced coders can probably manage with the alternatives, but newbies may struggle.
