Why do you 'have' to do this?  What are you actually trying to accomplish?

Pretend you can easily compute the matrix you want.  The amount of memory you'd 
need to store a single copy of it is so large, that all the computers in the 
world could not hold a copy of it.

So why is it that you think you have to do this?
