PLC MZI MATLAB仿真. MZI可用作波分复用器件（分离两个波长光信号）。本例子为一级MZI，由两个光耦合器（耦合系数a1,a2）和一段延迟臂（延迟dl）构成。MZI有两个输入和两个输出端口，一般两个波长光信号由一个输入端口输入，而在两个端口分别输出不同波长信号。(PLC MZI simulation.)

对于一个含有明显噪声的心电信号进行卡尔曼滤波处理，最大程度地 “还原”信号，达到去除噪声的目的。卡尔曼滤波（看成维纳滤波的一种实现方法）的特点如下： a) 是根据上一状态的估计值X(n-1)和当前状态的观测值Z(n)推出当前状态的估计值X(n)的滤波方法,不需要用过去的全部观测值。 b) 它是用状态方程和递推方法进行估计的，因而卡尔曼滤波对信号的平稳性和时不变性不做要求。 c) 使用全部观测值保证平稳性。(Kalman in matlab,if you need it,please download it.)

说明：  遗传算法matlab工具 1.工具箱文件拷贝至Matlab文件夹下，具体路径为：C:\program files\MATLAB\R2009a\toolbox。 2.工具箱路径加入Matlab文件路径之中。 流程为：File-->Set Path-->Add Folder。即，将C:\program files\MATLAB\R2009a\toolbox\文件夹加入该路径系统中。 3 重新启动Matlab，运行即可。 4 一般情况下，会出现如下情况。 安装遗传工具箱后出现问题：Warning: Name is nonexistent or not a directory: \afs\eos\info\ie\ie589k_info 解决方案： 将C:\program files\MATLAB\R2009a\toolbox\文件夹下的startup.m文件中的路径“\afs\eos\info\ie\ie589k_info\”改为goat当前所在的目录，“C:\program files\MATLAB\R2009a\toolbox\”即可。(Genetic algorithm matlab tool 1. Matlab toolbox files are copied to the folder, the specific path is: C: \ program files \ MATLAB \ R2009a \ toolbox. 2. Matlab toolbox add the file path into the path. Process is: File-&gt Set Path-&gt Add Folder. That is, the C: \ program files \ MATLAB \ R2009a \ toolbox \ folder by adding the path system. 3 Restart Matlab, can be run. 4 Under normal circumstances, there will be the following. Problems after installing genetic toolbox: Warning: Name is nonexistent or not a directory: \ afs \ eos \ info \ ie \ ie589k_info \ Solution: C: \ program files \ MATLAB \ R2009a \ toolbox \ startup folder under the . m file path &quot \ afs \ eos \ info \ ie \ ie589k_info \&quot to the current directory where the goat, &quot C: \ program files \ MATLAB \ R2009a \ toolbox \&quot can be.)

说明：  遗传算法在MATLAB环境中的实现,适合图形模式识别广泛应用等方面(Genetic algorithm implementation in MATLAB environment, suitable for wide range of graphics applications such as pattern recognition)
