Kalman Filter programmation

低通巴特沃斯滤波器设计求阶数，适合广大学生们参考，(Low-pass Butterworth filter design requirements order, for the majority of students reference)

说明：  一个关于主成分分析的matlab演示，十分有用(A principal component analysis on matlab demo, very useful)

人脸识别，根据所给出的照片进行筛选识别，找出最近似的那一个(face detection)

直流-直流变换器的matlab仿真模块，实现了直流降压的功能。(Matlab simulation of the DC- DC converter module, the function of DC buck.)

本书简绍了matlab编写有限元程序的整个流程(The goal of this document is to give a very brief overview and direction in the writing of nite element code using Matlab. It is assumed that the reader has a basic familiarity with the theory of the nite element method, and our attention will be mostly on the implementation. An example nite element code for analyzing static linear elastic problems written in Matlab is presented to illustrate how to program the nite element method.)

IIR Filter, hope it is useful

差分 微分模型的代码,很好用，学习很快。可尝试学习。(Differential differential model code, useful, learning quickly. You can try to learn.)

这是一个比较有用的小程序，能对被水印出理过的图象进行检测，效果很明显．(This is a relatively small program useful, can be a watermark image over the rationale for testing, the effect is obvious.)

To reduce the piracy .....here we use a watermark technique...
