This sounds like work.  ;-)

I'll shoot for putting something together this weekend.  I think Tim  
is right; we've been talking around in circles, and we need something  

I also think that a conjugate gradient algorithm, say, is high-level  
and doesn't require iterating over rows (or columns).  We should also  
look at (at least) one other algorithm, one that iterates over rows.   
I would suggest Gaussian elimination, unless this is too obviously a  
high-level functionality that should be part of the extension module.
