Then a completely filled memory with doubles (i.e. 8 byte floating point
numbers) is 4*1024^3/8 (if you have a 64-bit OS). But in order to do
something, the objects should not take more than 1/3 of your available
memory. Hence a matrix with 4*1024^3/8/3 elements seems to be a
reasonable upper limit.
