用这个小程序可以解杜芬方程，可以通过相图判断混沌状态，判断加入噪声和信号-With this little program can Xie Duffing equation to determine the phase diagram can be chaos, judge by adding noise and signal

用matlab对duffing方程进行求解，duffing方程是混沌算法的主要分支之一，具有效果较为良好的微弱信号检测功能。-Duffing equation is solved using matlab Duffing equation is one of the main branches of the chaotic algorithm with a the effect weak signal detection function.
