I am afraid my math knowledge goes only to a certain point here (too few it seems). In my usecase I am trying to define a terrain model from sparse points (lidar elevation points). So my idea was to get a set of points (given X, Y, Z) to define the parameters of the equation and then be able to calculate an elevation (Z) for any position I need interpolated. I would then expect to have an exact value once the parameters are defined. I am not sure how to find the parameters though...
