航迹控制 轨迹跟踪---船舶航迹控制，典型的欠驱动控制问题。(trackkeeping)

说明：  用于辨识,仿真,化工冶炼金属时控制过程曲面(for identification, simulation, chemical metal smelting process control surfaces)

说明：  用MATLAB实现对一语音信号用不同小波进行分解，提取各层的高低频系数，画出各系数波形，并重构。(MATLAB voice signal to a different wavelet decomposition, from the high levels of low-frequency coefficients. he painted the waveform coefficients, and Reconstruction.)

在科研中，大量时间花在统计年鉴的搜集上，例如找《中国城市统计年鉴》中2000多个市，要对分散的八个城市群找对应的数据，如果每次筛选会花费大量时间，如果做好excel表头，把对应的城市写上去会在多个文件多个工作组查找满足要求的数据，直接按需要保存成excel，进行后续分析。(In the research, the amount of time spent on the Statistical Yearbook of the collection, for example, to find " China City Statistical Yearbook" in more than 2000 cities and want to find a group of eight cities scattered corresponding data, if each screening will spend a lot of time, If you do excel header, the corresponding write up the city will look to meet the requirements of data in multiple files multiple workgroups, saved directly as needed to excel, for subsequent analysis.)

我写的一个小程序。用MATLAB自动生成任意维数和任意数量的数据，并且根据这些数据用一定的方法统计出这些点的概率密度。(I wrote a small program. MATLAB automatically generated using an arbitrary dimension and arbitrary amount of data, and based on these data in a certain way to the statistics of the probability density of these points.)

可以将matlab中的mat文件转换成txt文件，方便其他的应用程序调用。(Mat files can be converted into a txt file and facilitate the application calls.)

计算已知激励频率以及平板厚度情形下的Lamb波传播组群速度及相速度(calculate Lamb waves phase velocity and group velocity)

基于变量展开和主元时变协方差的MPCA的MATLAB小程序，希望对有需要的人有所帮助哈(based variable-wise unfolded multi-way MPCA)

基于模糊PID控制迟延系统具有更好的调节时间以及更小的超调量(The delay system based on fuzzy PID control has better adjustment time and smaller overshoot.)
