Operator[] works for eigen vectors, the following is taken from the online
documentation
"The operator[] is also overloaded for index-based access in vectors, but
keep in mind that C++ doesn't allow operator[] to take more than one
argument. We restrict operator[] to vectors, because an awkwardnes
Lei, could you explain why this particular part is important to you? As Roy
pointed out, for implicit apps this never shows up as a bottleneck, and for
JFNK work I think Derek agrees there are other hotspots? Why not address those
if performance is an issue?
I don't want to discourage the chan
Keep in mind the ability to add extra stuff to the sparsity pattern (using
AugmentSparsityPattern). That is something we rely on.
Also what is the current state of libMesh svn? I just got this compile

Hmm... how do you want to handle extra sparsity entries in the
distributed case?

We actually don't compute off-processor extra sparsity entries
currently. We do all the work to get all the info on the local
processor that the local processor needs to make decisions about
it's sparsity pattern and then just add the local entries.
