I wonder what is the difference between Matlab r2008a, r2008b, r2009a, r2009b, and r2010a? Are they for different OS? What is for Linux 32bit and what for Windows 7 32bit?
From: David Young on
They are different releases. The 4-digit number in the middle is actually a year in the Common Era. The OS is orthogonal to the release. See http://www.mathworks.com/ for details of operating system availability.
