Does anyone know if cftool can handle fits of data with more than 3 dimensions? i.e., hyperdimensional surface fits? Thanks in advance.

You haven't mentioned anything about splines in your original post, so I don't know where it fits into anything...
You need to supply a function which generates the hypersurface for any guess of the parameters.

Ok, thanks. That's what it seemed to me. Yes, this data does not fit any kind of closed-form model that I can think of very well. I've been using the cftool interpolation option for this data, and the "thin-plate" spline does a decent job. One day I'll try to write a hyperdimensional spline fitter, but I'm in kind of a hurry. Thanks for your help.
