Hi Zilin Wang,
由于我的母语不是中文，所以我用英语回答这个问题
The error could be caused by one of the following reasons:
- Licensing issue.
- Recursion in the "startup" MATLAB script: make sure that your "startup" M file is not causing the initializing error.
- It could be one of the toolboxes causing the issue. If the issue persists after trying out all the necessary troubleshooting steps, try reinstalling MATLAB with only a few toolboxes that you need and see if it solves the issue.
For detailed information on the error, its causes and troubleshooting steps, refer to the following MATLAB answer: https://www.mathworks.com/matlabcentral/answers/92566-why-does-matlab-get-stuck-in-the-initializing-or-busy-state-or-take-a-long-time-to-start
