附件中是我用Fortran写的lorenz混沌吸引子的lyapunov指数谱产生程序。包括三部分内容：如何产生lorenz吸引子，详细注释，如何计算lyapunov指数谱。 需要的话也可以单独提取子程序中的四阶龙格库塔算法。 希望有所用。-Annex is written in Fortran I used the Lorenz chaotic attractor of lyapunov index spectrum generation process. Includes three

solution of linear ODE by SHOOTING method Runge kutta

此程序是有关用四阶龙格库塔法计算微分方程的程序。-This program is the fourth-order Runge-Kutta method to calculate the differential equations of the program.
