将原图像用bior四层分解，之后弱化低频分量，重构原图，以得到细节。(use wavelet function(bior) to enhance the detail of the image,then reconstuct)

Introductory Finite Difference Methods for PDEs

说明：  用MATLAB实现的不合格品率P控制图的绘制，只要将数据导入data.txt文件，然后在MATLAB中运行main.m文件即可打开绘图界面。（注意：路径要设置好）(the failure rate of P Commodities Control Map, as long as the data into data.txt documents, then in MATLAB run main.m document can be open graphics interface. (Note : To set a good path))

故障诊断，包络解调分析，对于轴承故障诊断非常有效(Fault diagnosis, envelope demodulation, very effective for bearing fault diagnosis)

如何使用GUI那就下这个吧，可能对你有很大帮助呢(how do you use GUI， it can tell you ,don t lose it ,you can get something from it.thank you)

现代信号处理教程（胡广书），时频分析。含源码(time-frequency analysis)

说明：  自从发表《RS纠错编码原理及其实现方法》以来，收到很多初识RS编码的读者的来信， 大家纷纷表示这篇文章对初学者很有帮助，但同时也指出了很多不足。比如第一版的例子中都是按照码长 ， 但在实际应用中并不总是这种情况，还有就是MATLAB程序，由于作者在工程中是在DSP上用C实现的， 所以文章中的MATLAB程序只是用来说明问题，并没有经过调试。做事应该有始有终，这次修改， 附有详细的经过调试的MATLAB程序。并尽量做到程序具有通用性。(Since the publication of RS error-correcting coding theory and method, since the RS coding acquaintance received a lot of letters from readers, we have expressed this article helpful to beginners, but it also points out the many deficiencies. For example, the case of the first edition are in accordance with the code length, but in practical applications is not always such a situation, there is a MATLAB program, because the author works in the DSP using C to achieve, so the article in MATLAB program is used to describe the problem and not debug. Things should stay the course, this changes with the detailed procedures after debugging MATLAB. And as far as possible the procedures are inter-operable.)

IHOG, compute a 3D matrix of orientation histogram, storing a integral histogram for each pixel in the image

勒让德多项式德生成，在matlab 中德勒让德多项式不能直接用于求导数等计算，故可以自己定义(Legendre polynomials Germany generation, Dragulescu in Matlab which allow polynomials not be directly used for such derivative, it can own definition)

源代码中是三个子程序，分别为R,RRR,RRP,用于分析机构的各部分的速度，加速度，坐标。R用于分析原动杆，RRR用于分析双杆组构件，RRP用于分析两转动副一滑动副的双杆组。分析一个具体机构时可先将机构拆成原动杆和各杆组，然后调用这三个子程序来计算。(Source code of three subroutines, namely R, RRR, RRP, for the analysis of body parts of the velocity, acceleration, coordinates. R for the analysis of the original rod, RRR for the analysis of double-pole group member, RRP for the analysis of two revolute a sliding two-bar group vice. Analysis of a sector specific institutions can be split into the original first rod and the bar group, and then call subroutine to calculate the three.)
