public class AbstractInterpolation2D
extends java.lang.Object
implements Interpolation2D

Base class for 2-D interpolations.

Classes derived from this class will provide interpolated values from two sequences of length and , representing the discretized values of the and variables, and a matrix representing the tabulated function values.
