why Matlab don't use Swap but error "Out of memory"?

I was wondering why Matlab don't use Swap but throw out error "Out of memory"?

It should be slow instead of throw out error "Out of memory".

Because Java related something?

added:

I know "out of memory" means it's out of contiguous memory. and Swap doesn't have contiguous memory, or? I'm confused...

Swapping increases the available contiguos memory, but only until a certain limit. If this limit is exhausted you get the "Out of memory" error.

Even for a giantic virtual memory, a 32-bit Matlab version can access 4GB of RAM only. So please mention the version of Matlab and the OS.

Thanks! Btw, I also asked this question on stackflow.
