通过编程用多种方法完成数字图像的降噪处理，并进行比较分析。(Programmed with a variety of methods to complete digital image noise reduction processing, and comparative analysis. Enable students to more fully grasp the basic theory of image processing, principles and means of achieving a comprehensive analysis of certain issues and problem-solving ability.)

Multivariable sistem solution and simulink model

几个UKF和EKF例子，本来在工具箱中附带，后经修改，以便易于理解和适应稍有不同的需求。(several UKF and EKF demos,which were attached with KF toolbox, and revised according to tracing purpose.)

matlab程序，用遗传算法解决八皇后的问题。不用添加工具箱即可运行。其中yichuan.m是主程序。算法简单易懂。(matlab program, using genetic algorithms to solve the eight queens problem. Do not add Toolbox to run. Where yichuan.m is the main program. The algorithm is simple and easy to understand.)

卫星导航单点定位、伪距差分、载波相位差分RTK定位、卫导测姿、PPP等功能。(GNSS point positioning， pseudorange/carrier phase differencinal positioning， attitude determination。)

对声音信号进行处理，通过播放来检验处理效果，采用维纳滤波法进行滤波。有详细注解(voice signal processing, using weina.)

一个对几幅图象进行盲信号分离的MATLAB程序。 分离性能还不错。(The pieces of an image for Blind Signal Separation of the MATLAB program. Separation performance is not bad.)

求解无网格法的近似函数，（伽辽金无网格法移动最小二乘近似程序）(for non-grid method similar function (Galerkin grid Mobile least squares approximation procedures))

说明：  Matlab是科学计算与仿真中常用的工具软件，本文阐述Matlab编程中需要注意的问题！(Matlab is commonly used in scientific computing and simulation software tool, this paper, Matlab programming issues that need attention!)
