license到期肿么办？

二爷名声在外

这个内容之前也和大家分享过，现在专门开一个帖子说一下这个事情。土豪可以忽略，直接买正版。
最近，很多同学的matlab都出现了：

Your MATLAB license will expire in 60 days. Please contact your system administrator orMathWorks to renew this license.

针对这个情况，广大pj用户集思广益，主要有两种方法：
1。修改时间
基本思路是，建立一个bat文件，使计算机可以自动地先将日期改为一个足够早的日期，再启动Matlab，最后再恢复系统日期。
需要注意的是，bat文件应以管理员身份运行，而且bat文件中，在启动Matlab的命令之后，应做一定的延时（如3秒）再恢复系统日期。
大家应根据自己的系统的日期格式修改下面bat中的相应部分，其中要改的位置是年月日的顺序（包括是中间是短横分割还是右斜杠分割），以及matlab打开路径。只要系统时间是2017/09/22 形式的，都可以用这一段码。具体做法：先在桌面新建个记事本，把下面代码复制进去，再将记事本后缀修改为dat，之后要以管理员身份运行。

1. @Echo off
   
2. rem 保存当前日期
   
3. set y=%date:~0,4%
   
4. set m=%date:~5,2%
   
5. set d=%date:~8,2%
   
6. rem 将日期改为一个以前的日期
   
7. @date 2016/01/01
   
8. "D:\MATLAB\R2010b\bin\matlab.exe"
   
9. rem 延时
   
10. @ping 127.0.0.1 -n 15 >nul
    
11. rem 恢复日期
    
12. @date %y%/%m%/%d%
    
13.

2。重建注册文件
将以下文本复制并另存为license.lic到license目录
