非常有用的kalman滤波工具箱，含有很多matlab程序(Useful kalman filtering toolbox, containing a lot of matlab program)

变步长LMS滤波器做系统辨识，有详细注释，课运行(Variable step size LMS filter to do system identification, detailed notes, classes run)

matlab下将彩色图像装换为灰度图像的一个小程序(a small programm for convert the colour image to gray image using maltlab platform)

说明：  用MATLAB编程实现半导体光放大器（SOA）的ASE噪声特性分析，可以计算半导体光放大器的载流子密度，ASE增益，噪声指数，主要用的是半波逼近法来实现数值算法。(Programming with MATLAB semiconductor optical amplifier (SOA) of the ASE noise characteristics analysis, semiconductor optical amplifiers can calculate the carrier density, ASE gain, noise figure, the main use is half-wave approximation method to achieve the numerical algorithm.)

说明：  这是一个关于小波阈值图像去噪的程序，通过对分解后的系数各层进行不同的阈值处理，最后得到去噪后图像。(It s about a wavelet threshold program well worth beginners reference! )
