是一个基于Fortran语言计算 第一主应力 和 第三主应力 结构数值计算方便的代码(Fortran language is a calculation based on the first principal stress and the third principal stress code structure to facilitate numerical calculation)

说明：  Godunov格式和Roe格式求解Burgers方程(Godunov scheme and Roe scheme for solving Burgers equation)

说明：  所给的m文件中有详细的构造三对角分块矩阵的方法，而且构造的分块矩阵采用的是稀疏存储的方法，适用于大型三对角分块矩阵的构造(There are detailed methods to construct tridiagonal block matrix in the given m file, and the method of sparse storage is used to construct the block matrix, which is suitable for the construction of large tridiagonal block matrix.)

利用这个方法计算混沌时间序列的平均轨道周期p(Use this method to calculate the average orbital period of chaotic time series p)
