Check http://www.mathworks.com/discovery/matlab-gui.html for some details (with videos) on how to build a GUI. In your case, it seems clear - use GUIDE to create a GUI with an edit text box and a push button. If the former is named edit1 and the latter is named pushbutton1 then all you need to do is define the callback for the push button. Something like

 % --- 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)

 % get the value from the text box and convert to a number
 val = str2num(char(get(handles.edit1,'String')));

 % do some work using val

It may be that you need two edit text boxes if you are adding, subtracting or multiplying two numbers. Start with something simple and see what happens!

Hi,

What do I need to do if I want to get a numeric vector from the user in the edit text box?

[Geoff Hayes]

Daniel - are the numbers in the text box separated by spaces or commas? If spaces, why can't str2num be used (which should create a numeric array)?
