关于模拟退火遗传算法的MATLAB程序，欢迎各位下载学习，相互交流。(On simulated annealing genetic algorithm MATLAB program, welcome to download the study, each other.)

在matlab中实现矩阵的lu分解和Gauss-Seidel求特征值(Implemented in the matlab lu matrix decomposition and Gauss-Seidel eigenvalue)

Bairstow s approach is to use Newton s method to adjust the coefficients u and v in the quadratic x2 + ux + v until its roots are also roots of the polynomial being solved. The roots of the quadratic may then be determined, and the polynomial may be divided by the quadratic to eliminate those roots. This process is then iterated until the polynomial becomes quadratic or linear, and all the roots have been determined, bisection and other

自学编程的必备工具之一，建立简单的模型，可以通过建立模型来提高编程能力(Teach yourself programming tool, establishing simple model, can we establish a model to improve programming ability)

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。

通过这个实验，熟悉并能够灵活运用曲线回归或直线回归的方法去解决实际生活中的问题。(Through this experiment, familiar and flexible use of curvilinear regression or linear regression methods to solve real life problems.)

进行多尺度小波变换，能够得到较一般的小波变换更好的分解结果(Multi-scale wavelet transform)

说明：  一个使用ＦＤＦＤ方法计算光子晶体的例子，得到等效折射率的值。(a example of FDFD to caculate the PCF,and get the numerical of the N)

比较两个netcdf文件 1。通过添加内部ind2sub1函数remove函数依赖第三方 2。格式化文本(Description NCCMP compares two netcdf files and prints the differences. This function is useful for testing mathematical forecasting or prediction models. USAGE: NCCMP(ncfile1,ncfile2) NCCMP(ncfile1,ncfile2,tolerance,forceCompare) INPUT: ncfile1- name of the NetCDF file to compare ncfile2- name of the NetCDF file to compare tolerance- Compare numeric data using a tolerance threshold forceCompare- if false, exit when first difference is found true: continues to process all variables EXAMPLES: nccmp( old.nc , new.nc ,0.000001) nccmp( old.nc , new.nc ,[],true) FEATURES: 1. Print the differences and their locations 2. Exits when first difference is found or optionally continues to process all variables 3. User defined tolerance threshold to compare the variables TO DO: 1. Specific variable inclusion or exclusion 2. Specific attribute inclusion or exclusion 3. Option to ignore the history attribute 4. Ignore difference between v)
