5 exercices on Mechanics of solid materials for matlab: developments on graphs of shear and moment

说明：  Matlab网格划分程序可以将结构的四边形网格转换为三角形网格。 但该文件中内容重复了mesh2tri函数写了两遍，可以删除重复部分。 Demo: clear all close all clc (Matlab grid program 1. Create mesh grid 2. Plot the original rectangular mesh 3.1 forward slash division of quadrilateral)

matlab仿真中用s函数编写的信号频率测定程序(s function matlab simulation using test procedures prepared by the signal frequency)

matlab在通信原理中的应用，信道编码BCH码仿真，希望大家能用得上！(matlab in Communication Theory in the application of channel coding BCH code simulation, hope that we can useful!)

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印(Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection)

使用说明 1、所有仿真算法按章归类，光盘中的程序名与书中一一对应。 2、将光盘中的仿真程序复制到硬盘MATLAB运行的路径中，便可仿真运行。 3、本书算法在MATLAB 5.3版下运行成功，并适用于其他版本。 4、程序chap1_11.mdl；chap3_2.mdl；chap3_5.mdl；chap6_2.mdl；chap6_4.mdl需要在Matlab6.5下运行，特此说明。 5、假如您对仿真程序有疑问，请及时通过 E-mail 与作者联系。 北京航空航天大学 刘金琨 E-mail 地址： ljk@dept3.buaa.edu.cn或ljk@buaa.edu.cn(Instructions for use, all the simulation algorithms classified by chapter, program name in the CD-ROM and book one-to-one correspondence. 2, the simulation program in the CD-ROM copied to the hard MATLAB running path simulation can be run.
