产生线性调频信号，可以在编程时作为基本函数调用(Have a linear frequency modulated signal can be programmed as a basic function call)

本书第一章系统讲述 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、MATLAB 交互的功能。(This book first chapter of system narrated that the MATLAB6.5 integration working platform, guides the reader first meeting MATLAB essential usage. Second, third chapter of system narrate the MATLAB6.1 four big basic data type (value array, string of character array, structure cell array, skeleton array), as for other expansion data type (function handle, mark data, internal integration function, the unit array, sparse kind) in addition wards off the chapter to state specially. Hereafter, this book with nine independent Zhang Fenshu MATLAB6.5 numerical calculus, the mark computation, the function and the data visible, the object-oriented programming, GUI operates the contact surface design, the EXE independent application program generation, to realize different software platform interactive API, the M-book data graph writing environment integration alternately and so on eight big general functions. This book expounds the SIMULINK lamination modelling, the simulation function with prof)

小波包分析提取振动信号中的特征频率，供做算法研究人员参考，有较好的参考价值。( Wavelet packet analysis to extract vibration signal characteristic frequency, Algorithm for researchers to do reference, There are good reference value.)

进一步采用基于距离和曲线形态的双尺度相似性度量谱聚类算法进行聚类处理，通过求n 个二次规划问题，就可以求得相似度矩阵W，降低了谱聚类算法对参数的敏感性，使算法更稳定(Furthermore, we use the two-scale similarity measure spectrum clustering algorithm based on distance and curve shape to carry out clustering. By finding n quadratic programming problems, we can obtain the similarity matrix W and reduce the sensitivity of the spectral clustering algorithm to the parameters Sex, make the algorithm more stable)

Toeplitz矩阵的有关性质，用Matlab实现，有很强的参考价值。(Toeplitz matrices related to the nature, use Matlab to achieve, there is a strong reference value.)

G-P算法计算关联维的 Matlab 程序(mex版)(GP Algorithm for calculate correlation， Matlab program.)

说明：  MATLAB应用，做了一个图像特征提取程序，用来进行图像识别和区分(In matlab application, an image feature extraction program is made for image recognition and discrimination)

matlab要求编写函数，并画出图的matlab习题，供大家参考(prepared Matlab functions, and draws a plan of Matlab Exercise, for your reference! !)

说明：  基于模糊控制的避障仿真, 有图像，直线规划，能实现避障，但还不是很完美(Obstacle avoidance simulation based on fuzzy control, with image and straight line planning, can achieve obstacle avoidance, but it is not perfect)
