Description: 问题：用三次样条插值法求节点的函数值。
算法描述：
1． 以 为参数变量的方法（三弯矩方程）
用二阶导数值
来计算S(x)。
首由有条件构造函数 的线性表达式，然后对 积分，在利用连续性得到三次样条函数S(x)在区间[ ]上的表达式
式中 是未知参数。
由第一类边界 ,导出关于 的三对角方程组
=
式中，
k=1,2,…n-1
,
求出 后再代入S(x)得到函数值。
-Question: using cubic spline interpolation method node function value. Algorithm Description: 1. That the parameter variables (three moment equation) used to calculate the numerical second derivative S (x). The first constructor from the conditional linear expression, and then on the points to be continuity in the use of cubic spline function S (x) in the interval [] where the expression is the unknown parameters. From the first category boundaries, derived on the tridiagonal equations where =, k = 1,2, ... n-1, obtained after the substitution S (x) be function values.
