polyVal2D and polyFit2D

03 Apr 2013 (Updated 18 Apr 2013)

Evaluate 2D polynomials using Horner's method. Fit 2D polynomials to data using backslash operator.

File Information
Description	Often it's necessary to fit or evaluate a function with 2 dimensions. Use polyFit2D.m to fit a 2D polynomila to data and polyVal2D.m to evaluate it. Fun! These functions are explained in detail here: http://poquitopicante.blogspot.com/2013/03/horners-method-in-2d.html They are also hosted in a Gist on Github here: https://gist.github.com/mikofski/5159267
Acknowledgements	2 D Weighted Polynomial Fitting And Evaluation and Polyfitn inspired this file.
Required Products	MATLAB
MATLAB release	MATLAB 8.0 (R2012b)
