I have run into a similar issue before where the Command Window wouldn't appear in MATLAB Online. Here are the steps that helped me resolve it:
1. Try resetting the layout to bring the Command Window back into view:
- Go to the Home tab on the toolbar
- In the Environment section, click Layout
- Select Two Column (Default)
This often resolves display issues with hidden panels.
2. If resetting the layout doesn't help, your browser’s stored data might be interfering with the session.
For Chrome, see:
After clearing cookies, try reloading MATLAB Online.
3. If the issue still persists, the session data might be corrupted. Here's how to reset it:
- Go to: https://drive.matlab.com/files/
- In the upper-right corner, click your name and select "Show Hidden Files"
- Open the ".session" folder
- Delete all files inside this folder
- Reopen MATLAB Online.
This will force a fresh session and usually resolves persistent layout issues.
Hope this helps restore your Command Window in MATLAB Online.
