埃特金插值算法和追赶法求解三对角方程组，都是自己通过看书自己编写的，我个人觉得还是具有通用性的。-The Aitken interpolation algorithm and the catch-up method for solving tridiagonal equations are own by reading a book I have written, I personally think it has the versatility.

三次样条插值程序，这个需要配合追赶法来求解一个线性方程组。-Cubic spline interpolation procedure, this need with the catch-up method to solving a linear equation.

MATLAB求解混沌系统微分方程组，chen系统吸引子(MATLAB for solving differential equations of chaotic systems and attractor of Chen system)
