Matlab is supposedly in development for Intel and it's scheduled for release in early... er... Fall 2006... no wait, Spring 2007. Assuming they do not push back the release date further.
The beta program exists for professional users and students, and I'm lucky enough to have managed to sign on to the beta as a student. Will be getting my CD any time soon.
My experience with Mathworks is that they're a really $h!t company, and they've been sitting on improving the Mac port for years. Mathematica ported their suite to Mac OS X in 6 hours, while Matlab has taken over a year and a half to deliver the goods. It's a shame that Mathematica isn't as suited to numerical analysis, if not I'd switch in a heart beat. R for Mac OS X, which is free is far far more polished than Matlab for Mac OS X is, and I have doubts the 2007 release of Matlab will come anywhere close.
From my 3+ years of experience with Matlab, I honestly cannot recommend Matlab to anybody. Especially if they're on the Mac. If you've purchased the student version, you'll have to purchase a new copy if you want to get any service packs. Yes, you do not get free patches. You do not even pay a nominal fee for a patch. You pay the full price of a new copy for a service pack. Oh, and service packs break whatever toolboxes you have purchased, so you'll need to buy new versions too.
When R15 comes, sometime in 2007, students will be forced to pay the full price of a student copy again. If you want me to name a company that is the epitome of evil, it's not Microsoft. It's not Apple. It's Mathworks.
