关于MATLAB的一些应用实例，我同学编的，大家可以看一下(on MATLAB some application examples, I classmate series, we can look at)

这是基于哈尔滨工业大学的《线性系统》理论的课件，提供给大家！(This is based on the Harbin Industrial University, "Linear System Theory" courseware available to everyone!)

基于matlab的判决反馈的均衡器，通过此程序可以了解均衡器的基本编程方法(This program can understand the basic programming methods equalizer matlab' s decision feedback equalizer)

实测一组机械系统的振动信号，记录采样频率、采样点数，估计该组振动信号的均值、均方值、方差、自相关函数和功率谱，其中功率谱估计对比频率平滑与分段平滑的效率，针对分段平滑、分析不同平滑次数对功率谱估计的影响(Found a mechanical vibration signal system, the recording sampling frequency, sampling points, the estimated mean the set of vibration signals mean square value, variance, autocorrelation function and power spectrum, wherein the power spectrum estimation and comparison of frequency smoothing piecewise smooth efficiency for piecewise smooth, analyze the impact of different smooth frequency power spectrum estimation)

线性回归问题，内有简单matlab程序（可运行）以及PPT详解。(Linear regression, there are simple matlab (runs) and PPT explain.)

一个标准PCA的学习实例，通过matlab可运行，希望对大家有所帮助(A standard PCA learning instance, through matlab to run, we want to help)

支持向量机的使用方法和分类回归问题在matlab环境下的实现(SVM classification and regression problems using methods and in the realization of the matlab environment)

多项式的曲线拟合，使用MATHCAD实现(Polynomial curve fitting using MATHCAD achieve)

说明：  齿轮动力学，考虑的因素较多，有位移，法向力。(Gear dynamics, take into account many factors, displacement, normal force.Hopefully it will be useful)
