Comment (by vdelecroix):
Replying to [comment:22 nbruin]:
> In general, I think indeed that the generic matrix code shouldn't assume
equality- or zero-testing is particularly cheap, and hence avoid it unless
it's really necessary. The change here is a step in the right direction
and basically has the same effect of what rws was trying to do on his
branch.
Right, but for sparse matrices it is explicitely assumed that only nonzero
entries are stored... what should we do in that case?
