三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出。以第 1 边界条件为例，
用节点处二阶导数表示三次样条插值函数，用追赶法求解相关方程组。通过 Matlab 编制三次样条函数的通用程序，
可直接显示各区间段三次样条函数体表达式，计算出已给点插值并显示各区间分段曲线图。-Cubic spline interpolation function boundary condition for the practical problems cubic spline interpolation required to give the state the endpoint. In the first boundary condition, for example, with a node represents the second derivative of the cubic spline interpolation function for solving the relevant equations with catching method. General Procedure prepared by the cubic spline function Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation is calculated and displayed for each interval segment curve.
