测试matlab的程序时间，可以对比各种算法的执行效率，实用性很强哦(test time of program)

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)

经验模态分解 亲测好用，可以带入自己的数据(Empirical modal decomposition is easy to use and can bring in its own data.)

HHT方法的matlab程序集锦，里面包含了我做HHT方法结构识别时的全部程序(remove the noise of a signal)

时域序列x 和 h 的N点循环卷积子程序，用于matlab仿真调用(Time domain sequence x and h N-point circular convolution subroutines for the call of matlab simulation)

三种PN序列自相关性分析，和循环移位互相关分析gold，小m序列，walsh码(Three kinds of PN sequence from the correlation analysis, and rotate the cross-correlation analysis, contants gold, small m sequence, walsh code)

用HOMER软件画出的某地区一年每小时的风速，将其导出为文本格式，可导入到MATLAB中供研究人员使用(HOMER software to draw a region with a year hourly wind speed, export it to a text format that can be imported into MATLAB for researchers)

非常好用的matlab相机标定。可以自动估算出内部和外部参数(matlab toolbox for dot pattern based camera calibration. It estimates the intrinsic and extrinsic parameters of the cameras. The 3D model can be also refined via optional bundle adjustment)

RS纠错编码原理及其实现方法[第三版] 鉴于很多读者来信，特别是初学者对于如何求得RS生成多项式g[x]不是甚理解，特给出计算g[x]的MATLAB程序。(RS error-correcting coding theory and implementation methods [third edition] in view of a lot of letters from readers, especially for beginners on how to get RS to generate polynomial g [x] is not even understanding, give special calculation of g [x] in MATLAB procedures.)
