- 其基本思想是取B样条函数 为及基函数，在[a,b]中均匀划分区间，xi=a+ih,h=(b-a)/n,由于三次样条函数空间是n+3维的，所以把分点扩充到x-1,xn+1,则任意三次样条函数可用 线性组合来表示：-The basic idea is to take B-spline function and basis functions in [a, b] in the evenly divided intervals, xi = a+ ih, h = (ba)/n, because the c

- 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 interpol
