说明：  信号处理输入相关矩阵的创建程序以及傅里叶变换(Signal processing procedures for the creation of the input correlation matrix and Fourier transform)

对回转支承信号的处理，对时域内特征值得提取和主成分分析，计算第一主成分(For slewing ring signal processing, time domain feature extraction and principal component analysis is worth calculating the first principal component)

这是关于信号处理方面的知识，对matlab的卡尔曼滤波十分重要(This is knowledge about signal processing and it is very importance of kalman filter for matlab )

机器学习经典决策树算法的实现 输入训练标签输出预测结果(the classificial machine learning algorithm, input label and traning set and get predictions)

SFA算法的matlab实现，不是使用工具箱的那种，纯编程，望支持(The algorithm of SFA, not use the tool box function, use laugage of matlab.)

有关小波分解和小波重构方面的。用两个正弦波做例子验证的。(I think it can be use the signal processing.)

this is a method of watermarking. where SVD and DCT both are used to get robust and secure watermarking

基于matlab建立的关于汽车轴的控制模型，包括轴的运动方程和模型的建立。其实在ADVISOR中可以找到，不过，用matlab2012版重新建立了。(Established based on matlab axis control on the car model, including axis motion equations and model. ADVISOR can be found in the fact, however, re-established with matlab2012 version.)
