Curve fitting to a 3D polynomial with variable powers

I have 3 data sets. 2 for polynomial itself (let's call them x and y) and 1 for the function value (it's gonna be z). Polynomial looks something like this (assuming the power of both dimensions is 3): z = a00 + a01*x + a02*x^2 + a03*x^3 + a10*y +…
