Python contour map


where the drawing contourf (x, y, z), is obtained by using the python contourf function, where x is an array of dimensions 114, y is an array of dimensions 200, and z is an array of dimensions (114200).

I want to determine the coefficients of the n-dimensional (most likely second or third order) polynomials that best fit the data.

I have no problem doing this in 1D, but I have some trouble using 2D polynomials. I really appreciate some help.
