Class SmoothingBicubicSplineInterpolator

java.lang.Object

org.apache.commons.math.analysis.interpolation.SmoothingBicubicSplineInterpolator

All Implemented Interfaces:

BivariateRealGridInterpolator

@Deprecated
public class SmoothingBicubicSplineInterpolator
extends Object
implements BivariateRealGridInterpolator

Deprecated.

This class does not perform smoothing; the name is thus misleading. Please use BicubicSplineInterpolator instead. If smoothing is desired, a tentative implementation is provided in class SmoothingPolynomialBicubicSplineInterpolator. This class will be removed in math 3.0.

Generates a bicubic interpolation function. Before interpolating, smoothing of the input data is performed using splines. See Handbook on splines for the user, ISBN 084939404X, chapter 2.

Deprecated.

Computes an interpolating function for the data set.

Specified by:

interpolate in interface BivariateRealGridInterpolator

Parameters:

xval - All the x-coordinates of the interpolation points, sorted in increasing order.

yval - All the y-coordinates of the interpolation points, sorted in increasing order.

zval - The values of the interpolation points on all the grid knots: fval[i][j] = f(xval[i], yval[j]).

Returns:

a function which interpolates the data set.

Throws:

MathException - if arguments violate assumptions made by the interpolation algorithm.

IllegalArgumentException
