Hmmm, I don't understand your statement. Sorry. Anyway ...

I would also prefer to iterate over the nonzeros with appropiate iterators. That's
'cleaner' than working directly with the underlying arrays.

Are you doing the FE assembly process with a compressed matrix? If so, check
Gunter's hompepage for faster alternatives (general vector of vectors or so).
