MATLAB R2021b and R2022a:
You can turn off automatic suggestions and completions through the MATLAB Preferences:
- Go to the 'Home' tab in the MATLAB toolstrip and in the 'Environment' section, click 'Preferences'.
- Select 'MATLAB > Editor/Debugger > Automatic Completions' and in the 'Suggestions and completions' section, select the 'Show on tab' option.
- Click 'Apply' and 'Ok' to save the option.
You can also turn off automatic suggestions and completions in the MATLAB Editor itself:
- Click into any script and navigate to the 'View' tab
- In the 'Display' section, click the 'Automatic Completions' button off
The MATLAB Editor will now show suggestions and completions when the tab key is pressed, rather than showing them automatically.
Note: MATLAB versions R2021a and before do not support autocomplete on typing. However, suggestions and completions when using the tab key are still available for older versions.
