说明：  李氏指数的一些程序，希望对大家有用，啊哈哈和！(Lipschitz exponent of some of the procedures, we hope to be useful, ah ha ha and!)

用matlab分析处理了一段语音信号，实现了语音合成(Using matlab speech signal analysis and processing for a while to achieve a speech synthesis)

侦查法实现视频跟踪的matlab源代码 (Investigation of video tracking matlab source code)

Encryption of an image is done.The Encryption is based on Stream cipher.

这时极短软件抗干扰方面的程序代码，希望对大家有帮助。(very short time the anti-jamming software code, and I hope to be helpful.)

无线通信中，无线信道的模型的仿真程序，比较新，希望有所帮助(wireless communications, wireless channel model simulation program, a relatively new, hoping some help)

均匀平面波在无损耗媒质中传播时，平面波的电场与磁场的振幅之比等于媒质的本征阻抗，在理想介质中，阻抗为一正实数。因为电场、磁场方向始终不变，根据它们的值，利用MATLAB提供的实现动态轨迹.(Uniform plane wave propagation in the lossless medium, the plane wave of electric and magnetic fields is equal to the ratio of the amplitude of the intrinsic impedance of medium, in an ideal medium, impedance is a positive real number. Because the electric field, magnetic field direction remains unchanged, according to their values, provided by MATLAB dynamic trajectory.)

说明：  matlab 做图讲义，介绍如何使用matlab自带的命令画一维，二维，三维图形。(matlab study sourse)

【债券回购量化投资模型】：本人在投资公司做量化投资的，分享一个简单的债券回购量化投资模型，在rar压缩文件附有数据，模型的原理与策略系历史最大开盘价合约进场，细节不多讲，做量化投资的朋友可以了解一下。([Bond repurchase quantitative investment model]: I do quantitative investment in investment companies, sharing a simple bond repurchase quantitative investment model, rar compressed files with data, principles and strategy of the largest in the history of opening contract model approach , not much talk about the details, do the quantitative investment friends can look at.)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)
