k means techniques de classification non supervisée (clustering) les plus utilisées. Etant donné un entier K, K-means partitionne les données en K groupes, ou "clusters", ou "classes" ne se chevauchant pas. Ce résultat est obtenu en positionnant K "prototypes", ou "centroï des" dans les régions de l espace les plus peuplées. Chaque observation est alors affectée au prototype le plus proche (règle dite "de la Distance Minimale"). Chaque classe contient donc les observations qui sont plus proches d un certain prototype que de tout autre prototype

Implement a Rayleigh fading channel simulator based on the Filtered Gaussian Noise method

moravec角点检测的matlab实现(moravec corner detection matlab implementation)

说明：  本书是学习数值方法最新版本matlab实现的好帮手，详细而全的讲解及实现为自学matlab是一本不错的书籍。(This book is the latest version of matlab numerical methods to learn to achieve a good helper, detailed and full realization of the self-presentation as well as matlab is a good book.)

说明：  使用matlab实现信息瓶颈中的aIB算法源程序(Matlab implementation using information bottleneck algorithm source code in aIB)

作者在学习《航天系统》时，在c++6.0环境中实现的卫星定位的算法程序。包括通过轨道根数求卫星状态参数的算法和通过卫星状态参数反求卫星星历的算法。(Author of the study "space system" is in c++6.0 environment to achieve the satellite positioning algorithm. Including through the orbital parameters of the algorithm for the satellite status and Reverse status parameters via satellite satellite ephemeris algorithms.)

统讲述MATLAB6.5 的集成工作平台，引导读者初会MATLAB 基本用法。 第二、三章系统叙述MATLAB6.1 的四大基本数据类型（数值数组、字符串数组、元胞数组、 构架数组），至于其它扩展数据类型（函数句柄、符号数据、内联函数、unit 数组、稀疏类） 则另辟章节专述。此后，本书用九个独立章分述MATLAB6.5 的数值计算、符号计算、函数 和数据可视、面向对象编程、GUI 交互操作界面设计、EXE 独立应用程序生成、实现不同 软件平台交互的API、M-book 数据图形文字环境集成等八大通用功能。本书用专门的一章 深入浅出地阐明SIMULINK 的分层建模、仿真功能、与MATLAB 交互的功能。(The the integration work platform on the system tells MATLAB6.5 the guide readers to the beginning of MATLAB basic usage. The second and third chapters system described the MATLAB6.1 four basic data types (numeric array, string array, cell array, the array architecture), as extended data types (function handle symbol data, inline functions, unit array , the sparse class) are covered in separate chapters specifically mentioned. Since then, with nine separate chapter book are as MATLAB6.5 the numerical computation, symbolic computation, functions, and data visualization, object-oriented programming, GUI interactive interface design, EXE standalone application generation, different software platform to interact The data graphics API, M-book text environment integration Eight generic function. Book special chapter layman' s language to clarify SIMULINK hierarchical modeling, simulation capabilities, and MATLAB interaction.)

说明：  在三维空间中画泡泡,可以指定在三维空间中的x,y,z的坐标以及泡泡的半径r和颜色c(RGB).(BUBBLEPLOT3(x,y,z,r), where x, y, z and r are four vectors of the same length, plots bubbles of radii r in 3-space with centers at the points whose coordinates are the elements of x, y and z. If r is a matrix of size numel(x)x3, BUBBLEPLOT3 produces ellipsoids with centers x(i),y(i),z(i) and radii r(i,1), r(i,2) and r(i,3). BUBBLEPLOT3(x,y,z,r,c), where c is a rgb-triplet array (in [0,1]) with numel(x) rows, plots bubbles with colours specified by c. )

MATLAB的EMD工具箱，主要是对信号进行IMF分解，然后进行希尔伯特变换。得到信号的瞬时频率，并画出能量图。 使用是解压到matlab的work里面即可。(MATLAB toolbox of EMD, decomposition IMF, then Hilbert transform signal. The instantaneous frequency of the signal, and draw the energy diagram. Use extract to matlab can work inside.)
