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:
The matrix row and columns , sequences of and iterators:
BTW , with latest mods this *should* work with CVS and Review version of
Fusion... but no guarantess.
