Hello. My goal is to create a cell array variable from the inputs of the edit text box. For example,
name={'first input' ; 'second input' ; ...}
Is this possible or should I try a different approach on creating that cell array variable? If it's the latter, can you help explain that? Thank you.

Hi, actually I want the inputs to come from the same edit text box. For example, when the user enters 'john' and then reenters 'mike' (in the same edit text box), the output should become something like this:
name = {'john' ; 'mike'}
Can you help me with this? Thank you.

Initialize a variable. Each time the Callback on the edit box gets triggered, retrieve the variable and appened the new entry to the end of it, and save the variable away again.

I have problem with the newer input keeps overwriting the entered value before it (instead of adding it to the end of the array). Is there a way to avoid this?

if ~isfield(handles, 'saved_answers')
handles.saved_answers = {};
end
this_answer = get(hObject, 'String');
handles.saved_answers{end+1} = this_answer;
guidata(hObject, handles); %update master copy
