This MATLAB function creates a modal dialog box containing one or more text edit fields and returns the values entered by the user.

To have a MATLAB function wait for something to happen before continuing to execute, you can either use a different type of dialog box like QUESTDLG, which is blocking, or you can use the WAITFOR command in conjunction with MSGBOX, which causes MATLAB to ...
29 gru 2012 · You cannot prevent it from being closed, but you can use a while-loop to re-open it until the user has entered a useful value. done = false; while ~done. a=inputdlg('enter a number') num = str2double(a{1}); %# will turn empty and strings into NaN. if isnumeric(num) done = true; else. %# keep running while loop.
We are in the process of adding some gui elements to update one of our text based scripts. Some of the input values must be a number or an integer. With the input command at the command line, there...

Suppose I have a input box that requires an entry greater than zero before attempting to load a file. function test_Callback(hObject, eventdata, handles) test = str2double(get(hObject, 'String' ));
