Class BicubicInterpolator

  • All Implemented Interfaces:
    BivariateGridInterpolator

    public class BicubicInterpolator
    extends Object
    implements BivariateGridInterpolator
    Generates a bicubic interpolating function.

    Caveat: Because the interpolation scheme requires that derivatives be specified at the sample points, those are approximated with finite differences (using the 2-points symmetric formulae). Since their values are undefined at the borders of the provided interpolation ranges, the interpolated values will be wrong at the edges of the patch. The interpolate method will return a function that overrides BicubicInterpolatingFunction.isValidPoint(double,double) to indicate points where the interpolation will be inaccurate.
