基于DDE技术的Matlab语言上机考试平台的开发
摘要
随着科学技术在各个领域的深入发展，Matlab语言、LabVIEW编程系统等课程在高校的开设也越来越普遍。得益于计算机的普及和网络技术的发展，这些课程在教学过程中已开始实现理论与实际应用的结合，进入实验室和更多的实际运用领域。但是旨在检验教学成果的考试在无纸化的道路上却是举步维艰。在国外，一些发达国家网上考试己经得到蓬勃发展，已成为现代教育的有力补充，非常适合个性化学习。在国内，网上考试还处于试点阶段。目前进行的网上考试系统大体采用B/S（浏览器/服务器）和C/S（客户/服务器）两种模式。
本文介绍基于Visual Basic语言、采用C/S方式的Matlab语言上机考试系统的设计与实现。在这个系统中，学生使用基于VB的专用网上考试软件进行答题。考试软件的职能是负责与数据库的通讯和管理各种考试操作。我们所开发的Matlab上机考试平台是一个功能强大的平台。考生所有的抽题、编程、调试、保存和交卷都在上机考试平台上完成，简化了考生的操作。教师平台可以实现阅卷、运行代码、组卷和成绩统计等功能，方便教师对学生考试的管理。该系统将应用于我校的Matlab语言课程考试，目的在于提高教学效果和教学质量，并且该系统对于程序设计类课程的考试改革具有极其重要的意义。

Abstract
With the development of science and technology in various fields in-depth, it is increasingly common that programming language courses, such as Matlab, Labview, and so on, are set up in colleges and universities With the popularity of computer and the development of network technology, the theories have been combined with the practice in the teaching process of these courses And it is applied not only in the laboratory, but also in more practical fields But, the paperless process of the examination aiming to test the teaching effectiveness is very slow The Online Test System has flourished in some developed countries Meanwhile, it has become necessary complements in the modern education And it is also very suitable for individual learning In domestic, the Online Test System is still trial period Currently, the online examination system is usually based on B/S (Browser /Server) or C/S (Client/Server) mode
In this thesis, we will describe the design and implements of a Matlab Language Online Test System, which based on Visual Basic programming language and C/S mode In this system, candidates will use the above-mentioned, network-based test software to take the exam The functions of the test software are to response for communication with the database and management of the operation of the candidates The Matlab Language Online Test System we had developed is a powerful platform All procedures of an examination can be done, including randomly extracting questions, programming, debugging, saving and submitting the test paper, which simplifies the operation of the candidates On the teacher’s marking platform, teachers can mark papers, generate papers, run the code and record scores Therefore, it is convenient for teachers to manage the examination The system will be used to the Matlab Language Examination in our school aiming to improve teaching effectiveness and quality Meanwhile, it is extremely important to the reform of the Examination Process for the programming language courses
