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

modes of operation would be equivalent to polyval().
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.
I've attached my present copy of polyfit() and polyval(). They should
be compatible with the Matlab versions.
For those interested, please give them a try.
