此代码成学是在通信网理论中关于MATLAB仿真的实例(This code is in the communication network into a learning theory, on the MATLAB simulation examples of)

本代码包含遗传算法matlab工具箱中部分代码，与GAmat1.rar，GAmat2.rar，GAmat3.rar共同使用(This code contains the genetic algorithm matlab toolbox, part of the code, and GAmat1.rar, GAmat2.rar, GAmat3.rar common use)

作为算法实现的应用,对光子晶体光波导的电磁耦合效应进行了数值仿真研究,结果证实:波导耦合区域内不同半径比介质柱所导致的结构变化将造成耦合长度的改变,且其耦合关系曲线具有平稳区与迅变区两类不同特性的变化范围区间。(As the algorithm' s application, on the photonic crystal waveguide for electromagnetic coupling numerical simulation, results show: waveguide coupling region different than the dielectric cylinder radius of the structural changes caused by the coupling length will cause a change, and its coupling curve has a smooth area with the fast-changing area characteristics of two different range interval.)
