Class CubicSplineInterpolation2D

java.lang.Object

smile.interpolation.CubicSplineInterpolation2D

All Implemented Interfaces:

Interpolation2D

public class CubicSplineInterpolation2D
extends java.lang.Object
implements Interpolation2D

Cubic spline interpolation in a two-dimensional regular grid. It is similar to one-dimensional splines as it guarantees the continuity of the first and second function derivatives. Note that bicubic spline guarantees continuity of only gradient and cross-derivative.
