参数辨识程序，理论基础为递推最小二乘法，实现对系统参数的辨识(parameter identification)

电动执行机构是连接控制器与执行器(阀门)的部件，从控制出来的是离散信号，经零阶保持器后成为一个方波 信号，值都是阶跃跳动，而阀门的实际工作是有一定的行程时间的，即实际上阀门是不可能实现阶跃跳动的，故此需要一个电动执行器，将控制器的阶跃信号变为连续变化信号，假定阀门的行程时间与阀门开度变化成正比。(Electric Actuator is connected controller and actuator (valve) parts, from the control out of the discrete signal by zero-order cage became a square wave signal, values are step-beating, but the actual work of the valve there is a certain amount of travel time, that is, in fact the valve can not be achieved step beat, and therefore need an electric actuator, the controller of the step change in the signal into a continuous signal, assuming that the valve and the valve travel time changes in direct proportion to the door opening.)

這是簡單的MATLAB PROGRAM...適會初學者(This is a simple MATLAB PROGRAM ... would be appropriate for beginners)

采用matlab编写的对固定基座机器人动力学分析的程序，在simulink环境中运行。(Matlab prepared using a fixed base robot dynamic analysis procedures, in simulink environment.)

该代码实现的是压缩感知理论中的信号恢复问题。将压缩感知理论中的信号恢复问题转化为带参数约束的回归问题，从而利用贝叶斯理论实现参数估计，从而得到高效的重建稀疏信号。(The code to achieve the signal recovery problems in the theory of compressed sensing. Recovery issues into regression problems with parameter constraints will signal compression perception theory, Bayesian theory parameter estimation, resulting in efficient reconstruction of sparse signal.)

说明：  在工程里识别不同FSK和PSK的三阶循环特性的程序，其中最著名的算法！看通信调制识别的人一定看得懂(In engineering in different FSK and PSK to identify the third-order cycle characteristics of the procedures, most notably the algorithm! Modulation recognition of communication to see people must understand)
