The MatLab FIT function sf=fit([x y],z); plot(sf,[x y],z) is very useful for estimating 3D surfaces. However, in the case of sparse data and polynomial fitting, It generates interpolates that are unsuitable outside the 2D data boundary. My question is "how to trim (cut) the parts of surface that are outside the 2D boundary". Here, an example of unsuitable border fitting ...
