本程序通过SVD可以很好实现lyapunov指数计算，便于理解，且速度和精度较高(lyapunov exponent by SVD)

通过改变不同的频率，实现了使用Matlab播放音乐，因为示例为两只老虎和天空之城(By changing different frequencies, implemented using the Matlab play music, because the sample of two tigers and the Sky City)

this is a code for pso optimization method

DC Motor Thermal Circuit The demo illustrates how the thermal behavior of a motor can be simulated in lumped parameters.

这是一个关于多输入多输出系统的频域忙识别系统的matlab源码，作者基于二阶和更高阶统计，获得了比较良好的识别效果，文件中包含了文章，可参照起来理解源码。(This is one of the multiple-input multiple-output system in the frequency domain busy Recognition System Matlab source, Based on the second-order and higher-order statistics, access to a relatively good recognition results, the paper contains articles, can be read in the light source.)
