Single vs Double precisions is fine. Most of Matlab calculations are homework or simulations. Generally speaking the real world will add more errors then double floating points will reduce. Honestly GNU Octave has been a surprisingly fast developing product. Matlab only got GPU acceleration 2 years ago (according to my buddy who uses Matlab) (which is very fast for a GNU project). A lot of academics are picking up on it, even professors recommending it. I think the most glowing recommendation I heard was, "Well its free, and free goes along way when you're living on a research stipend."
