(Need Help) How to Obtain 2D Interpolation Coefficient?

I have a pre-setup 2D matrix whose size is [N x N].
Using this data, I want to find the each coefficient k in the below specific funtion.
z=k11*x^2+k22*y^2+...
k12*x*y+...
k1*x+k2*y+k0;
What's the simplest way to obtain these coefficients in Matlab?
It seems that the command 'interp2' does not provide these coefficients.

You have y on both the left and right hand side of the equation. Are they the same y or did you mean
z=k11*x^2+k22*y^2+...
k12*x*y+...
k1*x+k2*y+k0;
