EMD-Toolbox
EMD的Toolbox及使用方法
经验模态分解(Empirical Mode Decomposition, 简称EMD)是由美国NASA的黄锷博士提出的一种信号分析方法.它依据数据自身的时间尺度特征来进行信号分解, 无须预先设定任何基函数。这一点与建立在先验性的谐波基函数和小波基函数上的傅里叶分解与小波分解方法具有本质性的差别。正是由于这样的特点, EMD 方法在理论上可以应用于任何类型的信号的分解, 因而在处理非平稳及非线性数据上, 具有非常明显的优势。所以, EMD方法一经提出就在不同的工程领域得到了迅速有效的应用, 例如用在海洋、大气、天体观测资料与地震记录分析、机械故障诊断、密频动力系统的阻尼识别以及大型土木工程结构的模态参数识别方面。本工具书主要分以下几个部分:导论、非稳态信号介绍、一维时频信号分解、二维时频信号分解、时频影像信息提取等。
(Time frequency toolbox for use with MATLAB
The Time-Frequency Toolbox has been mainly developed under the auspices
of the French CNRS (Centre National de la Recherche Scientifique). It
results from a research effort conducted within its Groupements de Recherche
”Traitement du Signal et Images” (O. Macchi) and ”Information, Signal et
Images” (J.-M. Chassery). Parts of the Toolbox have also been developed at
Rice University, when one of the authors (PG) was visiting the Department
of Electrical and Computer Engineering, supported by NSF. Supporting institutions
are gratefully acknowledged, as well as M. Guglielmi, M. Najim,
R. Settineri, R.G. Baraniuk, M. Chausse, D. Roche, E. Chassande-Mottin,
O. Michel and P. Abry for their help at different phases of the development.)

SolvingODEswithMATLAB
This book is for people who want to solve ordinary differential equations (ODEs), both
initial value problems (IVPs) and boundary value problems (BVPs) as well as delay differential
equations (DDEs). Solving ODEs withMATLAB is a text for a one-semester course
for upper-level undergraduates and beginning graduate students in engineering, science,
and mathematics. Prerequisites are a first course in the theory of ODEs and a survey course
in numerical analysis. Implicit in these prerequisites is some programming experience,
preferably in Matlab, and some elementary matrix theory. Solving ODEs withMATLAB is
also a reference for professionals in engineering, science, and mathematics. With it they
can quickly obtain an understanding of the issues and see example problems solved in
detail. They can use the programs supplied with the book as templates.
