Dear Amir,

I suggest that you talk to a Mac expert to make sure that your Matlab is indeed 64-bit. From reading http://www.macworld.com/article/142379/2009/08/snow_leopard_64_bit.html it sounds like it's quite complicated on Mac and actually getting 64-bit is a combination of the right hardware, right OS and the right Matlab version and also they say that the OS can run programs in either 64-bit or a 32-bit mode. So perhaps although theoretically you should be ale to get 64 bit, in practice something goes wrong somewhere.

Best,

Vladimir

Dear Torben

It is an interesting command. I receive "MACI". So, it means that my Mac is 32bit, right? But am I still able to install 64bit MATLAB? Referring to the MathWorks web site http://www.mathworks.co.uk/support/faq/macintel64.html my OS and processors match the system requirements.

Have a good time,
Amir

Dear Robert

What happens if you type:

computer


at the matlab prompt? I you are running the 64 bit version you should get:

>> computer

ans =

MACI64

Dear Robert

Thanks for your reply. I'm working with Mac OS X 10.5.5 which supports 64bit MATLAB.

Have a good week :-)

What type of OS: windoze? Mac osx? Linux? Version of matlab?

To access memory you'll need 64bit matlab and appropriate os version. Check out mathworks website to get details.

32 bit can get you theoritically 4gig, but I believ 32bit windoze is built to only support 2gig

Your best bet is 64bit OS and 64bit matlab.

Hi :-)

One annoying problem. I so often receive the "Out of Memory" error message. I have 12GB of memory installed on my machine and most of the time it is free for at least 4GB. But I feel my MATLAB can't manage to use more than 2GB. What should I do? When ever MATLAB goes over 2GB of memory usage it gives me the "Out of Memory" error message and stops.

Have a good time,
Amir
