I don't know much about this stuff, but 640*210*1800*8 (one number takes 
8 bytes of memory on most 32bit machines) is approx. 2 GB of memory. I'm 
guessing that you can't allocate that much memory on your machine. On 32 
bit machines there is a hard limit on the amount of memory you allocate. 
I don't know this limit, but it's highly possible that you're hitting 
this limit. Is it possible that you can process your data in minor 
segments or possibly use integers to represent the data?
