out1 = [cell1,cell2,cell3,cell4,cell5];

cell0 = cellstr(cat(1,out1{:}))'

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 i
i=1

% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
global i
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
prompt = {'Enter your name'};
dlg_title = 'Name';
num_lines = 1;
def = {'','hsv'};
answer(i)=inputdlg(prompt,dlg_title,num_lines,def)
i=i+1

i am executing this above code. evert time user press push button 2 enter his name and store its name into answer. but instead of updating the answer it empties the previous names and just store the last name. how can i store every name into answer when user press push button 2 and enter his name. push button 1 is just to initialize i

cell0 = {cell1{:},cell2{:},cell3{:},cell4{:},cell5{:}};
cell0(cellfun(@isempty,cell0)) = [];

[Andrei Bobrov]

out1 = [cell1,cell2,cell3,cell4,cell5];
cell0 = out1(~cellfun('isempty',out1));

Your variable "answer" exists only within the workspace of the callback function, and is destroyed afterwards. If you want the information to be remembered you need to store it somewhere else. http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.3F

i cant get it into working can you help me with the code

[Walter Roberson]

handles.answer = answer;
guidata(hObject, handles);

Then, in another routine where you wanted to use the value,

answer = handles.answer;
