MATLAB: Prevent MATLAB GUI from opening when hitting a break point in command line mode

command linecommand windowguimatlab gui

I use MATLAB on my terminal using the "matlab -nosplash -nodesktop" command line option. However, when I enter debugging mode, either by hitting a break point or otherwise, the MATLAB debug GUI rears its ugly head and changes the window focus away from my terminal.

How do I prevent the MATLAB GUI from opening when using the debugger in -nodesktop mode?

Thank you!

Try Preferences -> Editor/Debugger and uncheck "Automatically open files when MATLAB reaches a breakpoint"

To prevent the MATLAB Editor/Debugger from opening a MATLAB file when encountering a breakpoint, turn off the "Automatically open files when MATLAB reaches a breakpoint" option in Preferences ->Editor/Debugger in MATLAB. Note this cannot be done via the command line.

When this option is selected, MATLAB opens the MATLAB file in the MATLAB Editor/Debugger or Emacs. External text editors are not integrated with MATLAB graphical debugging features. For more information regarding setting up Emacs as an integrated text editor in MATLAB, execute the following on the MATLAB command prompt:

MATLAB can be launched for use on the command line by passing it the command line flag '-nodesktop'. Commands can then be entered on the command line in the same way you would enter them in the MATLAB Command Window. Commands like 'plot' or 'figure' will still generate GUI windows.

By combining this functionality with a terminal multiplexing program like 'tmux' or 'screen', you can mimic the layout of the MATLAB desktop on the command line. You can then edit your files in vim while still having easy access to MATLAB commands to run and debug your script.
