Part of a book I am writing on mechanical vibrations.

巴特沃斯數字低通濾波器。採樣率8000HZ，fp=2100hz,fs=2500hz,Rp=3db,Rs=25db.(butterworth LPF)

说明：  关于gauusian函数的matlab代码，角点提取时会用到(About gauusian function matlab code that will be used corner detection)

This result model of ring resonator fiber optics, which has develop from ebook compendium ring resonator an author Rabus (2007) from spingerlink

基于matlab的EOF分解程序，包括旋转EOF分解，复数EOF分解等，附带详细的例子(matlab, including rotated EOF decomposition, plural EOF decomposition, etc., along with detailed examples)

局部均值分解(Local Mean Decomposition)，处理非线性非平稳信号的一个方法，LMD是依据信号本身的信息进行自适应分解(Local Mean Decomposition, a method for processing nonlinear non-stationary signals, LMD is adaptive decomposition based on the information of the signal itself.)

说明：  现代线性控制理论实验课程的原理，以及有关matlab的例子应用(Modern linear control theory, the principles of experimental program, as well as examples of application of the matlab)

该程序实现多特征自适应阈值算法，两个matlab文件，一个为函数，该函数求出信号的特征量值并通过梯度下降法训练出其初始阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其自适应阈值求出来，并一起画出图来。(The program features multi-adaptive threshold algorithm, two matlab files, one for the function,the function seek out characteristics value and initial threshold value of the signal by gradient descent , the other main function, called the function file the program seek out four signals , characteristics of each road and the adaptive threshold value,then draw them together on the map.)
