简单清淅的介绍了卡尔曼滤波的应用和基本源码，对初学者有很好的帮助。(Simple clearer introduces the application of kalman filtering and basic source, good for beginners.)

该程序是music谐波恢复算法仿真，由仿真结果证明music算法可以准确进行谐波估计。(The program is music harmonic retrieval algorithm simulation, the simulation results show that the harmonic music algorithm can accurately estimate.)

蒙特卡洛法对单个空间点的分析，及正态分布检测函数(Monte Carlo analysis method for a single point in space, and the normal detection function)

MATLAB M文件例子 最简单的精通MATLAB工具箱的函数之一提出了一个共同的问题。MATLAB函数gcf返回当前图形的句柄。但是，它有一个副作用。如果图形不存在，gcf就创建一个，并返回它的句柄。如果想寻找一个图形是否存在于头一个位置，要是没有，又不得不创建，怎么办？函数mmgcf正好实现由其内容所描述的工作。(MATLAB M file example of the simplest function of proficiency in one of MATLAB toolbox put forward a common problem. MATLAB function to return to the current GCF handle graphics. However, it has a side effect. If the graph does not exist, gcf on to create one and return its handle. If you want to find a graphic exist in the first position, if not, they have created, how should I do? Function mmgcf realize its content is described.)
