So I have a set of data points dependent on 2 parameters, ie: f(x,y)=z I am trying to take this set of data I have and generate a single equation I can use for any x,y in the data set. I've taken similar sets of data and generated curves for single-variable data sets, but this last one eludes me.
Any ideas on how to accomplish this, or how I could otherwise get some function to generate an output for any two given inputs?
This is intended to go into a programming application
