Yes exactly. In fact they're complex double to make matters x2 worse. Presently I crash out when I hit 2500x2500 although I'm sure I can get this higher by culling some waste and using some matrix relationships.

I do have another way around the problem which would be more amenable to swap files (exploiting FFTs and using Arnoldi diagonalisation) but I suspect it will be slower in practise until I get really, really large so I'm canvassing all interim ideas to see what I can squeeze out.
