How much physical memory do you have? How much is in use already at the time you try to create the array? If you are using MS Windows, what does the MATLAB command

memory

show you at the point just before you try to create the array?

Are you using 32 bit MATLAB or 64 bit MATLAB? Which operating system? Which MATLAB version?
