以rungekutta解ode，根據張鵬永老師的教法(Rungekutta solution to ode, according to Zhang Pengyong teachers teaching)

用wavedec2()函数对b1,b2两幅图像进行小波分解, 采用’haar’小波, 尝试着分解到第二或第三级 融合两幅图像。(With wavedec2 () function b1, b2 two images using wavelet decomposition, using haar wavelet, trying to break into the second or third grade fusion of two images.)

现有的代数特征的抽取方法绝大多数采用一维的方法，即首先将图像转换为一维向量，再用主分量分析（PCA）,Fisher线性鉴别分析（LDA）,Fisherfaces式核主分量分析（KPCA）等方法抽取特征，然后用适合的分类器分类。针对一维方法维数过高，计算量大，协方差矩阵常常是奇异矩阵等不足，提出了二维的图像特征抽取方法，计算量小，协方差矩阵一般是可逆的，且识别率较高。(existing algebra feature extraction method using a majority of the peacekeepers, First images will be converted into one-dimensional vector, and then principal component analysis (PCA), Fisher Linear Discriminant Analysis (LDA), Fisherfaces audits principal component analysis (KPCA), and other selected characteristics, then use the appropriate classification for classification. Victoria against an excessive dimension method, calculation, covariance matrix is often inadequate singular matrix, a two-dimensional image feature extraction method, a small amount of covariance matrix is usually reversible, and the recognition rate higher.)

本光盘是《数理统计与MATLAB数据分析》一书的配书光盘，内容包括了书中例题的源程序和应用程序(This CD is a book of mathematical statistics and MATLAB data analysis with the book CD-ROM containing the source of the book examples and applications)

轨道根数和位置的转换 naname和nadata是行星的名字和轨道根数(The the conversion naname nadata of the orbital elements and the location is the name of the planet' s orbital elements)

主动电流扰动法在并网发电系统孤岛检测中的应用(Of active current perturbation Law islanding detection of grid power system)

本书基于MATLAB 5.2版，提供了使用MATLAB的实践性指导。MATLAB已成为适合多学科、多种工作平台的功能强大、界面友好、语言自然并且开放性强的大型优秀应用软件，同时也已成为国内外高等院校高等数学、数值分析、数字信号处理、自动控制理论以及工程应用等课程的基本教学工具。本书按逻辑编排，自始至终用实例描述；内容完整且每章相对独立；是一本简明的MATLAB参考书，既适用于初学者，也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是所有MATLAB书籍中少有的一大特色。 本书适合作为理工科高等院校研究生、本科生教学用书，也可作为广大科研工程技术人员的自学用书。()

说明：  基于MATLAB的有限元分析工具箱，文件名即为函数运行名，其中包含了结构分析中需要的梁元、杆元函数，将工具箱解压到MATLAB工作目录后在路径中添加该文件夹路径即可。(The finite element analysis based on MATLAB toolbox, the file name shall be the function to run names, including the structure of the beam elements that need, member element function, MATLAB toolbox to extract working directory in the path to add the folder path can.)
