MATLAB Runtime Server

Preventing Command Window Input/Output

The MATLAB Runtime Server does not provide a command-line interface to the end user, so your application should not depend on the command window. To eliminate dependence on the command window, you should:

• Make certain that your application does not require input via the command window, and does not direct output to the command window.
• To avoid the need for command-line input, make sure the user can control the application solely through its graphical user interface (GUI). For example, if your application uses the MATLAB input function to acquire command-line input from the user, replace it with the inputdlg function, which uses a dialog box instead.
• To prevent command window output, trap errors where possible, and use the semicolon (;) operator at the end of statements to suppress the display of results to the command window. Use the GUI window, or additional figure windows and dialog boxes, to display results, error messages, help text, etc. See Trapping Errors for more information about handling errors. Also, see Setting the Global Warning Behavior on UNIX for information about UNIX warnings.

• If you need to use an evaluation function, then use evalc instead of eval, thus capturing output text. However, be aware that evaluation functions can make it more difficult to determine which files the application depends on. See Analyzing Functions Called by eval for information.

• Disable most or all default menu options on all figure windows that your application uses.
• (Recommended) To disable the default menus completely, set the figure's Menubar property to 'none'. You can still add your own menus.
• To disable some default menu options but not others, see Disabling Default Menu Options Selectively. This option requires you to maintain your application carefully if you use it with future versions of MATLAB. See the cautionary note in that section.
