MATLAB: I want to show the global variables IM and LBP in bae workspace from gui ????

global variablesgui

here this my first push button code,
in which IM is global variable
 % --- Executes on button press in pushbutton1.
 function pushbutton1_Callback(hObject, eventdata, handles)
 % hObject    handle to pushbutton1 (see GCBO)
 % eventdata  reserved - to be defined in a future version of MATLAB

 % handles    structure with handles and user data (see GUIDATA)

 global im im2
 [path,user_cance]=imgetfile();
 if user_cance
     msgbox(sprint('Error'),'Error','Error');
     return
 end
 im=imread(path);
 im=im2double(im);
 im2=im;
 axes(handles.axes1);
 imshow(im);
*******************************
And now is my second push button ,where IM and LBP are both global variables
 % --- Executes on button press in feature.
 function feature_Callback(hObject, eventdata, handles)
 % hObject    handle to feature (see GCBO)
 % eventdata  reserved - to be defined in a future version of MATLAB
 % handles    structure with handles and user data (see GUIDATA)
 %    close all; 
 %    clc;
 global im LBP;
 [r c]=size(im);
 LBP=zeros(256,1);
 offset= 3;
 LBPindex= 1;
 %binvect = zeros(8,1,'int32');
 coord = [1 1;1 2;1 3;2 3;3 3;3 2;3 1;2 1];
 for i=1:offset:r-1
     for j=1:offset:c-1
          win=im(i:i+(offset-1),j:j+(offset-1));
          counter=1;
          binvect = '';
          for k=1:1:offset
              for l=1:1:offset
                  if (k==2 && l==2)
                  else
                      tmpOne = '1';
                      tmpZero = '0';
                      if win(coord(counter,1),coord(counter,2))<win(2,2)
                          binvect =strcat(binvect,tmpZero);
                      else
                          binvect = strcat(binvect,tmpOne);
                      end
                      counter = counter+1
                  end
              end
          end
          %%inner for ends here
          %binary to dec conversion
          decimalValue= bin2dec(binvect);
          %calculate lbp histogram
          LBP(decimalValue + 1)= LBP(decimalValue + 1)+1;
      end
 end
i just want to show my global variables in main or base workspace

Best Answer

Wasif - if you want to write your variables to the base workspace, then use assignin as
 assignin('base','LBP',LBP);
 assignin('base','im',im);
where these two lines of code would be added to your second pushbutton callback.
Note that you don't need to use global variables when developing a GUI using GUIDE. Just save the variables to the handles structure in the first callback as
 handles.im  = im;
 handles.im2 = im2;
 guidata(hObject,handles);
And then, in the second callback, access these variables as
 handles.im
 handles.im2
to get to the values that were initialized in the other callback.
