Re: [PATCH] Add Greville abscissae functionality to B-splines


I'll add that I've never used Greville abscissae before, but did
do some reading about it when I looked at your patch. I also
found a matlab code on it which I used to verify some of your
test cases, which did look correct.

Maybe it would be worthwhile to back out this patch from the git
and do more testing on it first?

I'll be out of town for 2 weeks and won't be able to look at
your new patch until I get back.
