加算方法中的追赶法的例子，例子经过了最优化处理，可以最小开销的实现追赶法(Add count method to catch up with examples of law, for example, has been optimized to deal with, you can catch up with the realization of the minimum cost method)

MATLAB利用线性矩阵不等式解决控制系统的观测器设计问题并求解出了正定矩阵 (MATLAB linear matrix inequality solve observer design the control system and solved a positive definite matrix)

说明：  仿真已测试过，波形非常好。是双管正激电路参考的经典案例。(THAT IS THE GOOD DESIGN)

基于频率方差和子带分离的语音端点检测程序，基于matlab开发(based on specband var Vad detection programe,using matlab)

卡尔曼滤波器基本程序，适合初学者使用，一目了然(KALMAN filter)

gpr transmitter , and receiver , for ground penetrating radar

pope hinsken 算法可以无初值求取三维坐标转换参数(pope hinsken algorithm can do 3D coordinate transforming without a preliminary value)

瑞利信道的仿真，里面有瑞利的文档知识，仿真最后出瑞利分布的概率分布密度图和多普勒滤波器的频响图(Rayleigh channel simulation, which has knowledge of the Rayleigh documentation, simulation finally the probability distribution of the Rayleigh distribution density map and Doppler filter response chart)

用matlab做的频谱分析代码，值得学习一下(Use matlab to do spectrum analysis code, it is worth learning about)

matlab 本身没有箭头功能，只有梯度，梯度不能精确，这是编写的箭头功能，可以精确定位箭头三维位置(matlab function itself has no arrows, only gradient, the gradient is not accurate, it is written in the arrow function, you can pinpoint the location of the arrow D)
