Create and display an error dialog box
Syntax
errordlg
errordlg('errorstring')
errordlg('errorstring','dlgname')
errordlg('errorstring','dlgname','on')
h = errordlg(...)
Description
errordlg creates an error dialog box, or if the named dialog exists, errordlg pops the named dialog in front of other windows.
errordlg
displays a dialog box named 'Error Dialog' that contains the string 'This is the default error string.'
errordlg('errorstring')
displays a dialog box named 'Error Dialog' that contains the string 'errorstring'.
errordlg('errorstring','dlgname')
displays a dialog box named 'dlgname' that contains the string 'errorstring'.
errordlg('errorstring','dlgname','on')
specifies whether to replace an existing dialog box having the same name. 'on' brings an existing error dialog having the same name to the foreground. In this case, errordlg does not create a new dialog.
h = errordlg(...)
returns the handle of the dialog box.
Remarks
MATLAB sizes the dialog box to fit the string 'errorstring'. The error dialog box has an OK pushbutton and remains on the screen until you press the OK button or the Return key. After pressing the button, the error dialog box disappears.
The appearance of the dialog box depends on the windowing system you use.
Examples
