Problem :
What is the first Matlab release that fully supports 64-bit? Is it 2010a? I’ve got 64-bit installations of Linux and Mac OS X, and want to make sure I install a copy of Matlab that takes full advantage of 64-bit and the resulting larger memory support. Thanks.
Solution :
It appears to be there for Mac since R2009b release.MATLAB Release history. Also read, Why no 64-bit support for Mac OS?
For Linux, I am not very sure but it appears to be supporting 64-bit Linux even before it did in Windows i.e., since 2004. Relevant posts: 64 bit Matlab? and MATLAB Offers 64-Bit Support for MATLAB on Linux
