信号在噪声幅值为1000倍时的提取和数据处理，相关滤波器的设计(Signal in the noise amplitude is 1000 times as extraction and data processing, correlation filter design)

matlab中的龙贝格数值积分方法，可用来计算定积分，用户可更改里面函数(The matlab Romberg numerical integration methods, can be used to calculate the definite integral, the user can change the inside function)

Matlab GUI, 处理声音数据，下载声音数据处理后给予标识(Matlab GUI——sound，loads sounds and create time vector plot sound data and add a hightlight.)

手写数字识别程序，matlab运行前，先点击安装控件，内部有三种模型，GUI形式，使用方便(Handwritten numeral recognition program, matlab run before, first click on the installation of control, there are three kinds of models, GUI form, the use of convenience)

说明：  直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)

说明：  noma,ofdm,sim，采样特性研究，性能比较(noma,ofdm,sim,Research on sampling characteristics and performance comparison)

用矩量法计算细线天线的场分布，允许用户自行制定天线长度等参数．(Using moment method calculation of the field distribution of thin wire antennas, allowing users to establish their own parameters such as antenna length.)

matlab编写的聚类算法代码，包含常用的各种聚类方法，可以作为聚类的程序包，有很好的使用和参考价值(matlab for clusterings)

说明：  包含前馈与串级控制系统和前馈与反馈控制系统两个模型(Including feedforward and cascade control system and the feedforward and feedback control system the two models)
