在汽车门曲线设计中，运用三次样条插值法构造了严格对角占优的三弯矩方程组，利用追赶法求解方程组，并用Matlab进行了数值实验得到了数值解，汇出了曲线图，进而，我们将三次样条插值算法与分段线性插值、分段抛物插值、邻近点插值的结果进行比较，实验结果表明，三次样条插值算法能获得高精度的插值结果。

In the design of car door curves ,we used the method of cubic spline interpolation and constructed a ma-trix tridiagonal equations which is strictly diagonally dominant .And then we used the method of speedup substitu-tion to solve the equations .Meanwhile ,by means of mathematical analysis and simulation based on Matlab tool-box ,we got the numerical solutions and obtain the curve graph .Experiments showed that the spline interpolation can get high precision results .
