说明：  用MATLAB生成bpsk信号，并通过AWGN信道的仿真(MATLAB bpsk signal generation, and through the AWGN channel simulation)

This Program is used for calculating surface wave group velocity(This Program is used for calculating surfa ce wave group velocity)

模糊聚类的改进--先用减法聚类得到初始点，而后用模糊聚类得到聚类中心，能够提高聚类的速度和精度(Improved Fuzzy Clustering- first get the initial point subtraction clustering, and then get the cluster center with fuzzy clustering, clustering can improve the speed and accuracy)

This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust. It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0, i.e. it returns the vector A=(a,b,c,d,e,f). To convert this vector to the geometric parameters (This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.

自适应信号处理中 LSL算法 结合LMS算法 滤波程序(LSL algorithms in adaptive signal processing filter with LMS algorithm program)

多种对图像进行卷积运算的办法，利用了imfilter 和psf2otf函数等(severial kinds of connverlution methods using the psf2otf ,imfilter functions)

这是一个模糊pid控制的matlab程序。(This is a matlab program of fuzzy control pid.)

说明：  MATLAB 编写的用matlab 来实现的pde图像增强方法，如果不对的地方，请各位指出。(This is an enhance image example to use pde ways,if there is some problems ,please tell me )
