现实世界中有很多问题,它的机理较简单,用静态,线性或逻辑的方法即可建立模型,使用初等的数学方法,即可求解,我们称之为初等数学模型。本章主要介绍有关自然数,比例关系,状态转移,及量刚分析等建模例子,这些问题的巧妙的分析处理方法,可使读者达到举一反三,开拓思路,提高分析, 解决实际问题的能力。 在人们的生产实践中,经常会遇到如何利用现有资源来安排生产,以取得最大经济效益的问题。此类问题构成了运筹学的一个重要分支—数学规划,而线性规划(Linear Programming 简记LP)则是数学规划的一个重要分支。自从1947年G. B. Dantzig 提出求解线性规划的单纯形方法以来,线性规划在理论上趋向成熟,在实用中日益广泛与深入。特别是在计算机能处理成千上万个约束条件和决策变量的线性规划问题之后,线性规划的适用领域更为广泛了,已成为现代管理中经常采用的基本方法之一。 如果目标函数或约束条件中包含非线性函数,就称这种规划问题为非线性规划问题。一般说来,解非线性规划要比解线性规划问题困难得多。而且,也不象线性规划有单纯形法这一通用方法,非线性规划目前还没有适于各种问题的一般算法,各个方法都有自己特定的适用范围。 下面通过实例归纳出非线性规划数学模型的一般形式,介绍有关非线性规划的基本概念。

基于matlab的mp3的读写函数Mp3 toolbox for Matlab. Alfredo Fernandez Franco Aalborg University Departament of Acoustics M.Sc. Student aberserk@yahoo.com Includes 2 functions to write and read MP3 files. It works like the commands WAVWRITE and WAVREAD. 1.- Just unpack in the toolbox folder under the MATLAB directory. 2.- Set the MATLAB search path to include that folder. This version was made in MATLAB for WINDOWS only. I ll probably will make the UNIX version later. 01-11-2004.

UWB 功率控制 容量 Main Matlab script is in runsim.m. It generates random topologies, optimizes, and display results. IMPORTANT: you may need to add manually the lib path in Matlab in order to get all the necessary functions. Reference: Radunovic, Le Boudec, "Joint Power Control, Scheduling and Routing in UWB networks"

一般情况下,我们都是在MATLAB命令行或DOS命令行下编译MEX程序。 所用的命令就是:mex filename.c 这有很多不方便的地方: a. 虽然mex也可以编译C++的mex程序,但是它的主框架仍是C的 a. 当程序有多个模块时,需要多次使用mex命令,操作很麻烦 b. 不能利用VC特有的ClassWizard自动创建和维护类 c. 不能用MFC类库编写应用程序 d. 不能方便地进行类似VC的项目管理 本文详细解说如何在IDE中编译MEX程序

This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures). Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains "holes" that you should try to fill on your own. I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.

The MDP toolbox proposes functions related to the resolution of discrete-time Markov Decision Process : finite horizon, value iteration, policy iteration, linear programming algorithms with some variants. The functions (m-functions) were developped with MATLAB v6.0 (one of the functions requires the Mathworks Optimization Toolbox) by the decision team of the Biometry and Artificial Intelligence Unit of INRA Toulouse (France). The version 2.0 (February 2005) handles sparse matrices and contains an example
