So I upgraded to ML from SL and I'm pretty annoyed to discover my Matlab r2010 no longer works, so I guess I'll have to upgrade. I checked the mathworks store and it says under the system requirements that Matlab r2012a works with Lion, there is no mention of Mountain Lion. My question is does anyone have it? Someone must know if it works, I've searched but can't find a concrete answer. I'm also quite annoyed to discover that Mathworks don't even offer an upgrade option for previous customers. I have to pay full price again to get the latest version... a discounted upgrade option would have been nice since the software is pretty darn expensive. Meanwhile my friends pirate it and laugh at my inconvenience... not much incentive to pay for software is there.
