I have 3 set of data. I use cftool, to make an interpolation of theses, and I want to know the formula of the surface.
I use interpolant linear method.
And I have a nice surface on answer and this :
Linear interpolant : f(x,y) = piecewise lenar surface computed from p where x is normalized by mean 551.1 and std 72.04 and where y is normalized by mean 1.499 and std 0.9631
Coefficients : p = coefficient structure
Goodness of fit: SEE : 4.093e+09 R-square : 0.9979 Adjusted R-square : Nan RMSE: Nan
My goal is to have the formula of the surface, like that I can find the third parameter when I know 2 of them.
