Hi all, I have just upgraded from 2020a to 2023a, and I do not know how to remove these two new additions to either side of the editor. The break line column was 3 "units" wide, and I was able to get it down to 1 "unit" wide, but I have a small screen, so any screen space is expensive real estate! Thanks in advance!

Hey @Andrew Phillip
I understand you want to remove the line numbers and error message column in the MATLAB Editor, you can follow these steps:
  1. Open MATLAB and go to the "Home" tab in the MATLAB Desktop.
  2. Click on the "Preferences" button in the "Environment" section of the toolbar. This will open the "Preferences" dialog box.
  3. In the left-hand pane of the "Preferences" dialog box, expand the "Editor/Debugger" category.
  4. In the right-hand pane, under the "Display" section, uncheck the "Show line numbers" option. This will remove the line numbers column in the editor.

  1. In the left-hand pane of the "Preferences" dialog box, expand the "Code Analyzer " category.
  2. In the right pane uncheck the “Enable integrated warning and error messages”
  3. Click the "OK" button to save the changes and close the "Preferences" dialog box.
