(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.
What's the simplest way to obtain these coefficients in Matlab?
It seems that the command 'interp2' does not provide these coefficients.

If you have the Curve Fitting Toolbox, you can follow this example
except you would use the 'poly22' model instead of 'poly44'
If you don't have the toolbox, then see one of these FEX submissions.
