I would like to fit a function to a parabolic surface with translation and rotation. I am using custom equation inside the curve fitter. I have created the equation, but it seems that it cannot be fitted with complex value. My goal is to get the RMSE of the surface which I am trying to fit.

Use the nonlinear fit with least squares method lsqcurvefit() - see this documentation:
