pca程序，PCA可以用于图像处理等方面(pca procedure)

This program performs the Duane growth method with least-squares fit of an input data set to a straight line

利用维纳滤波对信号进行分析处理，包括代码与word文档(Wiener filtering using the signal analysis and processing, including code and word documents)

从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

利用三轴角速率型号和三轴加速度计信号结合扩展卡尔曼滤波实现三个姿态角度的融合(The use of three-axis angular velocity model and three-axis accelerometer signal extended Kalman filter combined with the realization of the integration of the three attitude angles)

关于数字信号处理的matlab程序实现代码，有很多实用的方法，如功率谱估计的算法等等，对学习数字信号处理很有帮助(On digital signal processing matlab program implementation code, there are many practical ways, such as power spectrum estimation algorithms, etc., is helpful in learning digital signal processing)

用MATLAB读取obj格式的三维文件，实现了把obj读入matlab中并以点的形式储存，可以参考学习(Read obj format 3D files using MATLAB, obj read into matlab and to the point in the form of storage, you can refer to learning)

说明：  用matlab编写的多尺度散布熵程序，还保存精细多尺度散布熵程序(The program of multi-scale dispersion entropy written by MATLAB also preserves the program of fine multi-scale dispersion entropy.)

光纤通信中用来计算相对误差的matlab源程序，对于刚入门的人有很大的帮助。(Optical Fiber Communication is used to calculate the relative error of the matlab source code, for people who have just started a great help.)
