The only thing that appears to agree with Matlab is the result from

If you (anyone?) has insight into how the algorithm for polyconf()
should be written, feel free to pick apart the one I posted.
Meanwhile, it does appear that we now have a polyfit() and polyval()
which respect the scaling, and whether or not a solution for fixing
the polyconf(), I'll rewrite polyval() to work independently of it.
Do you know

There's a lot of documentation linked from there, especially

Someone with some knowledge in statistics around?
