用于插入nastran提交文件.bdf文件中提取出基于偶极子网格法求的气动影响系数矩阵(It is used to insert nastran submission file and extract aerodynamic influence coefficient matrix based on dipole mesh method from BDF file)

（本文是在论坛已有一篇文章《SIRP法相干相关K分布雷达杂波的建模与仿真》的基础上修改而来，在此首先感谢这篇文章的作者给予我的帮助。之所以完成这篇文章，有三个方面的原因：一是对原文章和仿真程序代码明显存在一些不一致的地方，因此，我这里对每个公式进行检验（后来证明文章的公式正确无误，但所给的仿真代码存在问题），二是对自己近4天工作的一个总结，以便以后学习可以参考；三是可以放在网上给初学者一些参考，以便后来者不再走自己曾经走过的弯路。文章的一些文字是在匆忙间完成，只求能表达所述意思，没有详细斟酌，海涵：））((This article is an article in the forum have been "SIRP law related coherent K distributed clutter radar modeling and simulation" on modified from the foundation, in this first of all thank the authors of this article has given me help. The reason why the completion of this articles, there are three reasons: First, the original article and simulation program code, there are some obvious inconsistencies, so I here the formula for each test (later proven formula article is correct, but give the simulation code problem exist), near two of their four days of a summary of the job in order to study the future reference three on-line can give some reference for beginners in order to go was no longer the tortuous path they have traversed. article of some language is in a rush to complete, only to express the meaning as described, did not elaborate, as appropriate, Haihan:)))

说明：  在abaqus中生成cohesive element visual studio中使用C++开发 内附使用说明(cohesive element creat for abaqus C++ development in visual studio Instructions for use included)

verilog写的LnE算法，可用于计算指数和对数(Verilog written in LnE algorithm, can be used to calculate the index and the logarithm)

MFC 扩展DLL 编程实例 搭好了一个进行编程的框架(The MFC extension DLL programming example sets up a framework for programming)

本程序可对EXCEL文件进行读写，同时建立了一个专门访问EXCEL文件的类CExcel，可供大家参考。(This procedure can be carried out on the EXCEL file to read and write, while the establishment of a specialized type of access EXCEL file CExcel, for your reference.)

说明：  PSO-BP代码，实现模型预测，这是最基础的模型可以进行修改优化(PSO-BP code to realize model prediction, which is the most basic model that can be modified and optimized)
