Class WireSurfacePiecewiseConstant

java.lang.Object

org.drip.spline.multidimensional.WireSurfacePiecewiseConstant

public class WireSurfacePiecewiseConstant
extends java.lang.Object

WireSurfacePiecewiseConstant implements the piecewise Constant version of the 2D Spline Response Surface. It synthesizes this from an array of 1D Span Instances, each of which is referred to as wire spline in this case.
