说明：  本案例给出了振动信号的时域信号分析，fft分析，低通滤波分析和Hilbert包络分析代码，并将分析结果展现在一个图中进行对比。(This case gives the time domain signal analysis, FFT analysis, low-pass filter analysis and Hilbert envelope analysis code of vibration signal, and shows the analysis results in a figure for comparison.)

matlab高级编程的所有源程序,以章节为单位，源程序很全(all program of matlab )

Kalman滤波程序及其相关资料，对于理解Kalman滤波十分有用，而且Kalman滤波的界面是基于MATLAB设计的。(Kalman filtering procedures and related information useful for understanding the Kalman filter and Kalman filtering is based on the MATLAB interface design.)

说明：  我们知道，小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。以下是一维小波分解的程序. (We know that a wavelet transform decomposition process is that the original signal were low-pass, high pass filter, and then carried out under the binary sample, we obtained low-frequency, high-frequency (also known as the average, details) coefficient of two parts and Multi-level decomposition is a decomposition of the previous low-frequency coefficients to be further wavelet decomposition is a recursive process. Following is a one-dimensional wavelet decomposition process.)
