Umut,
although not well advertised you may want to try to construct your
matrices using a generalized_vector_of_vectors and then copy it to the
final format (I think this is the fastest in Guntler's examples).
that option seems to be the fastest indeed, I will investigate that
approach soon.
It usually works better in random assignments, but I am
not sure this will work for you.
Your timings suggest that you do, but I would like to remind to use
-NDEBUG in your compilation options.
yes, I use -DNDEBUG -O3.
