无法启动或卸载MATLAB R2019b
显示 更早的评论
我使用的版本是南京大学MATLAB校园版R2019b，成功安装之后打开时总是弹出“fatal error on statup”窗口，下面显示这样一大串文字：

I'm from NJU, too and I'm also facing this problem. Have you ever solved it yet?

Hi,
Refer to solution provide in this thread: Error Starting Desktop (java.lang.NullPointerException)-WIN10-Matlab R2019a
if not, go through this thread: Why will MATLAB not start up properly on my Windows based system?
and see if this resolves the issue.

The second answer you mentioned says:
1. Right click on the MATLAB shortcut and choose properties.
2. Go to the end of the "Target" line, after MATLAB.exe, and add the flag -nodesktop. For example:
"C:\Program Files\Matlab\R2016a\bin\matlab.exe" -nodesktop
But i cant find 'target' after starting properties, why?

快捷方式里面有一个目标(T)，后面是路径，我试了但是提醒我路径不对，也没有用。
