Exactly what i was looking for
03 Oct 2011 2D Weighted Polynomial Fitting and Evaluation Two scripts: polyfitweighted2 fits 2D data with weights, and polyval2 evaluates the 2D polynomial Author: Salman Rogers babaei, milad

would somebody plz explain me on that those script algorithm??how does code work (does the least square )???

Very useful program, only a few issues with memory usage creating the very large grid of zeros length(x)*length(y) by length(p). Could possibly be improved with a catch routine to check if the memory usage is too high and split the (x,y) grid into 4 or 9 etc and apply the program multiple times.
This is just nitpicking though it's a very good program.

In the help comments for polyfitweighted2, it says that Z and W should be of size [length(X) length(Y)]

However, throughout the code (both polyfitweighted2 and polyval2, Z and W are treated as though of size
 [length(Y) length(X)].

Very useful. Matlab should build it in.
