matlab and simulink. this book book is primarily intended for first semester engineering students who are looking for an introduction to the MATLAB and Simulink environment oriented toward the knowledge and requirements of beginning students. Thus, only a few basic ideas from mathematics, in particular ordinary differential equations, programming, and physics are required to understand the contents of this book. This knowledge is usually acquired in the first two or three semesters of a technical engineering degree program. Under these conditions, this book should also be of interest for practicing engineers who are looking for a brief introduction to MATLAB and Simulink. In the case of this book, engineers will have the knowledge required to understand it years after they have finished their studies.

在matlab环境下利用LSB最低有效位算法将一个图片水印隐藏在载体图片中，并对被隐藏那个信息进行提取。(Matlab environment in the use of least significant bit LSB algorithm will be a picture watermark hidden in the picture carrier, and that information has been extracted hidden.)

运用打靶法求解二阶边值问题。 A1*d/dx(dy/dx) + A2*dy/dx + A3*y + A4 = 0(To illustrate the use of Runge-Kutta method in the Shooting method as applied to a function of the user s choosing.)

本文主要是描述的DDC的matlab功能，从输入的信号经过1/4fs搬频，然后半带抽取，再到混频，最后到分数倍的抽取，再经过成形滤波器输出。(digital down convention)

说明：  用MATLAB实现的QPSK调制和解调程序。(Using MATLAB to achieve the QPSK modulation and demodulation process.)

通过边界集中识别图像形状特性，并返回数值(Images by identifying the boundary shape characteristics of centralized and return values)

说明：  使用matlab调用refprop，计算各种制冷剂工质的物性数据(refprop used in matlab)

Multi-class Coding (adapted from from LS-SVM for SPIDER). Encode (code_MOC, code_ECOC, code_OneVsAll, code_OneVsOns) and decode (codedist_hamming, codedist_bay) a multi-class classification task into multiple binary classifiers.
