　　本文提供了一个分析　　复杂的动态显示当前模式控制　　开关电源转换器。电流型控制的提高　　转换器与非线性分析和研究　　离散建模方法已被使用。通过改变　　电路参数、混乱和复杂的行为　　分歧发生在开关电源转换器。为　　增加稳定period-l操作范围,坡道　　已经被改变其使用和补偿方法　　转换器的边坡,其效果将被显示。最后, 　　最大平均Iyapunov指数不同的斜坡上　　审查和模拟。(The present article provides an analysis of complex dynamics displayed by current mode controlled switching dc-dc converter. Current-mode controlled boost converter has been studied with nonlinear analysis and the discrete-time modeling approach has been used. By changing circuit parameters, complex behaviors like chaos and bifurcation occur in the switching dc-dc converter. For increasing stable period-l operation range, the ramp compensation approach has been used and by changing its slope, its effect in the converter will be shown. Finally, the largest average Iyapunov exponent for different slopes is reviewed and simulated)

IEEE 802.16d路径损耗模型属于对数正态阴影路径损耗模型。根据郊区宏蜂窝中发射机和接收机之间的障碍物密度，可以分为三种类型ABC。该代码利用MATLAB仿真了IEEE 802.16d路径损耗模型，并画出了未修正和修正的模型曲线以供对比参考。(IEEE 802.16d path loss models are lognormal shadow path loss model. According density suburban macrocell obstacle between transmitter and receiver can be divided into three types A B C. The code using MATLAB simulation of the IEEE 802.16d path loss model, and draw the uncorrected and corrected model curve for comparative reference.)

说明：  不变矩是模式识别里面很重要的一种技术，它可以用于提取不变性特征，从而进行模式识别，广泛用于图像处理当中，如图像特征匹配(Moment invariant pattern recognition which is a very important technology that can be used to extract invariant features for pattern recognition which is widely used in image processing, such as an image feature matching)

本书把 MATLAB 当作一种技术编程语言来教，向学生展示如何编写简洁高效，有充分 根据的程序。本书不主张把 MATLAB 数以百计的函数全部介绍给大家，而是教给学生怎样使用 MATLAB 语言，以及如何使用网上在线工具去加载你所需要的函数。(The book MATLAB as a technology programming language to teach, show students how to write simple and efficient, have fully According to the program. This book does not advocate the MATLAB hundreds of function is introduced to you all, but teach students how to use MATLAB language, and how to use the online tools you need to load the function.)
