## Homework Statement

Hello guys, I have a set of data containing x and y coordinates(width and length) as well as a 'z' coordinate that represents power density at each point of x and y given. I was hoping that someone might be able to help me figure out a way that I can find a function for z in terms of x and y given all of the data points. Perhaps matlab or mathematica has a way of doing it, although I have not found it yet. I will include a snapshot of some of the data although it is extensive. Also, the number of width data points are larger than the number of length data points if that makes a difference. Thank you very much

Polynomial function for z in terms of x and y given the data[/B]

## The Attempt at a Solution

Looked around the web for quite some time on how to figure this out without brute force and couldn't find any solid answers.
