in reply to Re: (zdog) Re: (2) Estimating continuous functions
in thread Estimating continuous functions

I took (or tried to take) a look at cubic spline interpolation, and a lot of the implementations seem to be for sets of (x, y) pairs. Adding the additional dimensions scared me off a bit.

Either way, I do have some sort of idea of what the first function I have to do this for looks like. I'll describe it as best as I can (perhaps someone can help me improve my terminology to do so) .. but here it goes:

This particular function has 3 independent variables, so it would look something like this: F(x, y, z). (Later on, I will need something that can handle even more.) As x is varied and the other variables are kept constant, the function is logarithmic. And as either y or z are varied and the other variables are kept constant, the function takes on a form similar to e**(k/x).

Any ideas or pointers where to go from here?
