3D Least squares polynomial fit in x and y 1.0 
Date Added: July 17, 2013  Visits: 308 


Often, measured data is comprised of N sampled values of z, evaluated at N locations (x,y). With this function, you can calculate the coefficients of the bestfit x,y polynomial using a linear least squares approximation.You can use this function if you have a set of N data triplets x,y,z, and you want to find a polynomial f(x,y) of a specific form (i.e. you know the terms you want to include (e.g. x^2, xy^3, constant, x^3, etc.) in your fitting polynomial.
