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。
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;
软件介绍:MATLAB是美国MathWorks公司旗下的一款数学软件，该软件将数值分析、矩阵计算、科学数据可视化以及非线性动态系统的建模和仿真等诸多强大功能集于一体，为科研和工程等众多领域提供了一种全面的解决方案，且一定程度上摆脱了传统C、C++等程序设计语言的编辑模式。
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。
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.
