I agree .. this is kind of sucky. There was a (short) thread (I  
think) a few weeks ago that had mentioned something about doing more  
work on the sparse matrix stuff, but I can't seem to find it.

The day when we'll have a unified interface to normal/dense matrices  
and sparse matrices will be a great day indeed ... well, ok, at least  
a pretty darn good day ...
