      • value

        public double value​(double x,
                            double y)
                     throws OutOfRangeException
        Compute the value for the function.
        Specified by:
        value in interface BivariateFunction
        Parameters:
        x - Abscissa for which the function value should be computed.
        y - Ordinate for which the function value should be computed.
        Returns:
        the value.
        Throws:
        OutOfRangeException
      • isValidPoint

        public boolean isValidPoint​(double x,
                                    double y)
        Indicates whether a point is within the interpolation range.
        Parameters:
        x - First coordinate.
        y - Second coordinate.
        Returns:
