    public class BicubicSpline
    extends Object
    implements BivariateGridInterpolation
    Bicubic splines are the two-dimensional equivalent of cubic splines. In this two-dimensional case, for each of the N columns of grid values, an one-dimensional spline z(xi, y) is constructed. To interpolate the value of a point (a, b), N values at b (i.e., z(xi, b)) are first obtained from the column splines, Then, an one-dimensional cubic spline interpolation is performed on those N values to interpolate the value at (a, b) (i.e., z(a, b)).

    Like in the one-dimensional case, natural splines are constructed.
