I've only played a little bit with the matlab compiler, but my experiences 
indicated (and some googling of comp.soft-sys.matlab seemed to back this 
up) that the compiled, matlab generated C code is no faster than the 
"source" .m files.  It *does*, of course, alleviate the issue of 
licensing (err, at least I think it does -- it's been a while), but it 
sure doesn't buy you any speed.
