Using Button Group in MATLAB GUI

Asked by Peeyush

on 31 Mar 2012


I am trying perform this action using MATLAB GUI: i) Create a button group with 2 radio button ii)Based on user's selection, a variable (say, num) gets assigned a value ('1' for radiobutton1 and '2' for radiobutton2) iii) Output this variable with the user's selection to MATLAB workspace using OutputFcn

I am able to assign a value based on user selection to 'SolutionMethod', but I get an error in the OutputFcn: _ Error in ==> TrialGUI3>TrialGUI3_OutputFcn at 91 function varargout = TrialGUI3_OutputFcn(hObject, eventdata, handles)_


1) How do I remove error?

2) How do I get the value of 'num' variable to MATLAB workspace?

Here's my MATLAB code:

% ---------------------------------------------------------
% Executes just before TrialGUI3 is made visible.
function TrialGUI3_OpeningFcn(hObject, eventdata, handles, varargin)
% Choose default command line output for TrialGUI3
handles.output = hObject;  
% Update handles structure
guidata(hObject, handles);
% UIWAIT makes TrialGUI3 wait for user response (see UIRESUME)
% uiwait(handles.figure1);
% --- Executes when selected object is changed in uipanel1.
function uipanel1_SelectionChangeFcn(hObject, eventdata, handles)
switch get(eventdata.NewValue,'Tag') 
% Get Tag of selected object.
    case 'radiobutton1'
        % Code for when radiobutton1 is selected.
        num = 1;   
    case 'radiobutton2'
        % Code for when radiobutton2 is selected.
        num = 2;
        % Code for when there is no match.
% --- Outputs from this function are returned to the command line.
function varargout = TrialGUI3_OutputFcn(hObject, eventdata, handles) 
% varargout{1} = output.handles;
% --------------------------------------------------------------
% uipanel1: Tag for button group
% radiobutton1: Tag for radio button 1
% radiobutton2: Tag for radio button 1

Thanks in advance for your help.
