duffing分岔图，计算连续duffing方程Lyapunov指数的程序,比较好用-duffing bifurcation diagram, duffing equation for calculating the Lyapunov index procedure, comparative ease of use

计算上田阵子的最大利亚普诺夫函数的matlab源码程序, 是确定系统的常微分方程。-the matlab code is using to caculat duffing the max lyapunvo about determined duffing system .

可以模拟大部分分数阶混沌系统的matlab代码，如分数阶Duffing方程，分数阶Lorenz方程等(The matlab code of most fractional order chaotic systems can be simulated, such as fractional Duffing equation, fractional Lorenz equation and so on.)

本代码用matlab编程，计算了duffing振子（杜芬振子）和非线性加幂律振子的响应，使用的方法是Newmark β方法和Runge-kutta方法，资源内容包括matlab代码和演示PPT，仅供学习使用，有问题可以留言。(This code uses MATLAB programming to calculate the response of Duffing oscillator and nonlinear plus power-law oscillator.)
