Subject: multidimensional (smoothing) splines
Hi,
I am approximation a value function (in dynamic programming) V:
R^n->R. In different versions of the problem, n is between 2 and 5.
I would like to use splines to use this, I checked the mailing list
and CRAN but couldn't find anything that would help me (Tps in fields
is too slow, cobs would be really nice but seems to be
one-dimensional). Is there any package that would at least give me
the basis for multidimensional b-splines? Or even one that would do
the fitting, perhaps even with constaints on derivatives at the edges
(which I can specify from theory)?
Thank you,
Tamas
