首先，打开MATLAB编辑器,输入该文件中程序码，把文件保存到MATLAB当前目录并命名为zhuangxiang.m,只需在命令窗口中输入zhuangxiang,按回车键，根据提示输入，便可解决贪心算法中货船装箱问题，以求得最优解。 (First of all, open the MATLAB editor, enter the file, program code, save the file to the MATLAB current directory and named zhuangxiang.m, simply type in the command window zhuangxiang, press the Enter key, according to prompts can be solved by greedy algorithm cargo bin-packing problem, in order to achieve the optimal solution.)

Koch曲线、Sierpinski三角形、Cantor集的MATLAB实现代码 含结果图(Koch curve, Sierpinski triangle, Cantor set of MATLAB implementation code contains the results of Figure)

求解约束优化问题的极小值问题，在给定区间内求函数的最优值(Minimum problem solving constrained optimization problems, in the optimal value within a given interval demand function)

the Bag of Visual word ( BoV/BoW/BoF ) representation of an image or video

with this code it could drwa evrythings about modal parametrs of structures and otherthings

我写的重要代码,一个关于matlab，制作用户界面的程序，很好的学习代码(IT IS VERY USEFUL， about the matlab and other languages.it is very useful.On matlab, the production of user interface procedures, good learning code)

地球物理勘探中重力资料解释的主要目的是由地表观测值推断地下可能存在的密度分布。众所周知,任何一组重力数据都可能由无数个密度分布所引起。即使假设了重力异常是由具有均匀密度差的单一地质体产生的,也得不出唯一的解(Gravity geophysical exploration data interpretation main purpose is inferred from surface observations may exist underground density distribution. Is known, any set of data may be provided by gravity density caused numerous. Even assuming that the gravity anomaly is determined by having a uniform density difference arising from a single geological body, they have no unique solution)

说明：  经典图书Courant, Hilbert - Methods of Mathematical Physics Vol. 1 50年不倒的经典图书，值得一看，是学习数学物理方法的经典名著(Classic books Courant, Hilbert- Methods of Mathematical Physics Vol. 1 50 will not be brought down in the classic books, worth a visit is to study methods of mathematical physics classics)

粗糙集属性约简过程中的下近似及上近似域的matlab实现(Rough set attribute reduction under the approximation of the process and on the realization of similar domain matlab)

本书简绍了matlab编写有限元程序的整个流程(The goal of this document is to give a very brief overview and direction in the writing of nite element code using Matlab. It is assumed that the reader has a basic familiarity with the theory of the nite element method, and our attention will be mostly on the implementation. An example nite element code for analyzing static linear elastic problems written in Matlab is presented to illustrate how to program the nite element method.)
