平面波展开法求解二维光子晶体能带结构源程序(Two-dimensional plane wave expansion method to photonic crystal band structure)

制作有使用日期限制的程序。此程序虽然复杂有更好的方法，但可以锻炼思路加强语法！(Production procedures have been used the date restriction. This procedure, although the complex has a better way, but they can exercise ideas to strengthen grammar!)

本程序的功能是用牛顿——拉夫逊法进行潮流计算。程序为10节点，10支路。供研究电力系统潮流的人员参考。(This procedure is the function of the Newton- Raphson method flow calculation. Procedures for the 10-node, 10 branches. Power Flow for research officers.)

说明：  the linear ARX model as shown below [12] is used to represent the input and the output data for the system. This ARX model is utilized for both Least Square (LS) and Recursive Least Square (RLS) algorithms. It is one of the simplest statistical methods for system identification used to find the transfer function for the model. The equations given by [15]: Y=φβ+ξ (7) β=〖(φ^T φ)〗^(-1) φ^T Y (8) where Y is the predicted output. φ is includes actual input and output parameters. β is includes parameters to be estimated.

本压缩文件包含HHT-EMD(希尔伯特黄转换－经验模态分解)发明人黄锷院士领衔之台湾中央大学数据分析方法研究中心推广的标准EMD/EEMD/CEEMD分析工具，由该中心资深研究员Yung-Hung Wang王老师于2013年撰写，包含了原始EMD及近年来EMD的最新算法，最为权威、快速、精确、易用。 本人目前在该中心访学，对原文档进行了两处更动：1、加入程式注释中提到的5篇参考文献，以方便使用者随时参考，深入理解算法的意义；2、将eemd.m第111行代码getDefaultStream改为getGlobalStream(该行注释中已附参考链接)，解决了Matlab2013后的新版本在此运行出错的问题，旧版本用户可改回原代码。 纯干货，诚挚推荐。(fast EMD/EEMD/CEEMD code)
