java.lang.Objectorg.apache.commons.math.analysis.interpolation.SmoothingBicubicSplineInterpolator
BicubicSplineInterpolator
instead. If smoothing is desired, a tentative implementation is provided in class
SmoothingPolynomialBicubicSplineInterpolator
.
This class will be removed in math 3.0.
@Deprecated public class SmoothingBicubicSplineInterpolator
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.
