实现关联矩阵与邻接矩阵相互转化的matlab代码(Correlation matrix and adjacency matrix to achieve mutual transformation of matlab code)

利用遗传程序设计建立电力系统的负荷模型，无需像传统方法一样预先确定具体的模型结构，它能根据输入输出数据直接演化出变量间的函数关系，并且能够一次性的同时确定函数的结构形式和参数，使得模型的生成过程趋于智能化、自动化，解决了负荷建模工作中长期困扰的模型辨识问题。(Genetic Programming(GP) is a new evolutionary algorithm based on genetic algorithm,which has self-adaptive,self-organizing,self-learing and other advantages.As a kind of automatic programming technology,it tries to study the computer how to solve the problem according to the objective enviroment automatically without human intervention.)

说明：  这个文件夹里包括有计算分数阶混沌的几个算法，对于用matlab进行分数阶混沌的研究很有帮助。(This folder includes the calculation of the number of fractional order chaotic algorithms, for use matlab to the study of fractional Chaos helpful.)

This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys. Lett. 70 3218 There are 3 programs, one for short, one for elastic long and the other one is for acoustic long(This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys.
