用matlab编写的有限元程序，可用于解偏微分方程的数值解(Using matlab finite element program can be used to solve the numerical solution of partial differential equations)

实现用systerm generation 完成fft变换。原理清晰，但是结构相对复杂，请大家认真看原理，来自日本书。(Systerm generation completed using fft transform. Principles of clarity, but the structure is relatively complex, please look carefully the principle of everybody, from the Japanese book.)

简单的matlab控制PID程序，可以运行，对初学PID很有用(PID control simple matlab program, you can run, PID is useful for beginners)

Test Template Class Source Code for Andriod.

语音信号处理的端点检测程序，在编程中调用，很实用，值得你一看。(Endpoint detection)

Gauss elimination method to solve system of equations

几种基于小波变换的图像边缘提取程序，该程序中有对几种边缘提取程序进行比较，对于初学者或者小波变换编程刚入门的同学比较有帮助(Several wavelet-based image edge detection program that has several kinds of edge extraction procedures were compared, for beginners or transform just started programming more helpful to students)

自然频率越高的情况下，对传统的部分影响越高，经过模糊处理却不受影响，但是自然频率调整的越高时，阻尼比反而要降低，这样模糊处理过的状态才不会受到影响，由此可见，自然频率与阻尼比在模糊控制中有相对的关系。(The relative relationship between the natural frequency and damping ratio in Fuzzy Control)
