6月6日开始，逐渐有哈工大的学生发现，MATLAB软件似乎出现了问题。6日当天使用MATLAB时，界面会弹出反激活通知，点击反激活选项后能够继续使用，但到了第二天，直接显示授权许可无效，也无法继续登录哈工大域名的账户。
We mentioned earlier that Opricovic proposed the VIKOR decision-making method in 1998， which is a compromise ranking method， which compromises and ranks limited decision-making schemes by maximizing group utility and minimizing individual regret values. It is used in the following situations:Decision makers cannot accurately express their preferences;从之前的学习中我们可以学习到，在Matlab界面的脚本中，需要使用关键字if有条件地执行代码段。
由Guido van Rossum 设计开发，其第一版于上世纪九十年代发布，发展到到现在Python在全球数千贡献者的合作下，已经发展成为一种成熟的编程语言，主要版本有python 2.7 和 python 3.0版本;
As a powerful， easy-to-use and flexible computational tool， MATLAB not only has a wide range of applications in science and engineering， but also plays an important role in education and research. Its rich functionality， easy-to-use interface and extensive support make it one of the preferred tools in many fields. With MATLAB， users can easily perform complex mathematical operations， data analysis and algorithm development， which promotes the development and innovation of science and technology.
本文将介绍Matlab的两个实用技巧。一键生成Word版本的报告和PDF版本的数学试卷。其中第一个技巧Matlab之前都是通过调用COM接口来实现的，类似于VBA，虽然可做的事情很多，但并不适合一般的童鞋。第二个技巧，灵感来源于一位研究僧同学。
