Matlab is commercial software. As such, the vendors should have the authoritative idea on what operating system is best for it. You are paying vast amounts of money for it, so get some value for that money and contact them. They might not have tested it on the latest Ubuntu, or maybe they don't even support Ubuntu and you'll have to switch to Redhat Enterprise. Who knows? They do, and you've given them money. Lots of money.
Don't just rely on stuff you read on the internet for commercial software. Get the support from the vendor.
