You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: MFquestdlg.m
    path of file: ./repos/automagic/src
    
    the code of the file until where you have to start completion: function ButtonName=MFquestdlg(Pos,Question,Title,Btn1,Btn2,Btn3,Default)
% MFQUESTDLG Question dialog box.

%  --------------------- Modified Function Help ----------------------
%  ‘MFquestdlg’ is a simple modification of ‘questdlg’ which enables user
%  to specify the position of 'questdlg' question dialog box on the screen.
%  Everything is like the original ‘questdlg’, except that you need to determine
%  your desirable position with a two-element vector of the f
    
function
%  call.  If custom button names are entered, the default button
%  must be specified by adding an extra argument, DEFAULT, and
%  setting DEFAULT to the same string name as the button you want
%  to use as the default button:
%
%    ButtonName = questdlg(Question, Title, Btn1, Btn2, DEFAULT);
%
%  where DEFAULT is set to Btn1.  This makes Btn1 the default answer.
%  If the DEFAULT string does not match any of the button string names,
%  a warning message is displayed.
%
%  To use TeX interpretation for the Question string, a data
%  structure must be used for the last argument, i.e.
%
%    ButtonName = questdlg(Question, Title, Btn1, Btn2, OPTIONS);
%
%  The OPTIONS structure must include the fields Default and Interpreter.
%  Interpreter may be 'none' or 'tex' and Default is the default button
%  name to be used.
%
%  If the dialog is closed without a valid selection, the return value
%  is empty.
%
%  Example:
%
%  ButtonName = questdlg('What is your favorite color?', ...
%                        'Color Question', ...
%                        'Red', 'Green', 'Blue', 'Green');
%  switch ButtonName,
%    case 'Red',
%     disp('Your favorite color is Red');
%    case 'Blue',
%     disp('Your favorite color is Blue.')
%     case 'Green',
%      disp('Your favorite color is Green.');
%  end
