Yes, I have now linked to the code on this page:
I have also put there, notes about what I have done already and what
remains to be done, along with test output and so on.
I should warn you that most of my time have been spent so far on the
nuts&bolts of getting things working in spad (All the small issues,
like I found that I needed to use NNI to index a vector and SINT to do
bitwise logic and since I needed to use the same integer for both I
had to work out when I needed to force a conversion) so I have had
very little time to understand the maths.
So this means that some of the algorithms don't give correct result
yet (especially non-diagonal case).
However, with that warning in mind, I would appreciate and feedback
about whether I am on the right track and any hints to help me
