Description: 三次样条插值，三次样条函数:
定义:函数S(x)∈C2[a,b] ，且在每个小区间[ xj,xj+1 ]上是三次多项式，其中
a =x0 <x1<...< xn= b 是给定节点，则称S(x)是节点x0,x1,...xn上的三次样条函数。
若在节点x j 上给定函数值Yj= f (Xj).( j =0, 1, , n) ，并成立
S(xj ) =yj .( j= 0, 1, , n) ，则称S(x)为三次样条插值函数。-Cubic spline interpolation, cubic spline interpolation, cubic spline interpolation
