[ADMB Users] Cubic splines

[Derek Seiple]

All the documentation sources listed are the only ones I know of. Is
there an example where the cubic spline isn't working as expected? Or
is it more of trying to get it to work the way you want?

If there is an example that isn't working I can try to look at it with
in the next couple of days and see what I find.
