无法启动或卸载MATLAB R2019b

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：

have you save the problem

[KE SU]

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

[Guichen Zhang]

Sorry, I don't know how to solve this so I gave up at last.

Answer 1

[Akshit Agarwal]

Hi,

Refer to solution provide in this thread: Error Starting Desktop (java.lang​.NullPoint​erExceptio​n)-WIN10-M​atlab 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.

[Guichen Zhang]

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。
