joint_view is a prime example of a segmented sequence. The resulting iterators from it will have some overhead. That is inevitable. See joint_view_iterator so you'll know what I mean.
I don't get it. Fusion iterators know their position at compile-time. Why should there be any overhead?
FWIW The various sequences and iterators are here. This is all just a first hit. I am sure that there is much room for improvement. However currently I want to move on to other things, but I have done enough here ( and in the links to examples previous in the thread) to prove that a fusion matrix would be a very worthy addition to Fusion. I reckon with the use of static_values that it would be the fastest thing around. And BTW sorry to be rude about MTL4 but unfortunately I can't see that my comments are wrong, and if all just wait for the rollout then nothing is going to happen, is it? The matrix definition: http://tinyurl.com/kwfvd The matrix row and columns , sequences of and iterators: http://quan.cvs.sourceforge.net/quan/quan-trunk/quan/fusion/boost/ BTW , with latest mods this *should* work with CVS and Review version of Fusion... but no guarantess. regards Andy Little
