POGlobal variables set in GUI with no values - Matlab
text
Body
copied!<p>I created a GUI to set parameters and use those parameters in another m-File. I know that the variables created in GUI are in a different workspace from the input variables to the m-File. For that reason, I'm trying to use <code>global variables</code>, but not sucesfully: the variables goes to the m-File empty.</p> <p>I have a GUI which has 3 edit boxes, that the user can set parameters (0 or 1), using this code (showing the code for only one edit box):</p> <pre><code>function density_Callback(hObject, eventdata, handles) % hObject handle to density (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) % Hints: get(hObject,'String') returns contents of density as text % str2double(get(hObject,'String')) returns contents of density as a double global density density = str2double(get(hObject, 'String')); global Variavel_1 assignin('base', 'Variavel_1', density); </code></pre> <p>The m-File are called from a GUI BUTTON, using this code: </p> <pre><code>function calculate_Callback(hObject, eventdata, handles) % hObject handle to calculate (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) test %m-File that uses variables set in GUI </code></pre> <p>And the m-File should use this <code>Variavel_1</code> and the others from the remaining editboxes in this code (test.m):</p> <pre><code>global Variavel_1 global Variavel_2 global sum Variavel_1 Variavel_2 sum = Variavel_1 + Variavel_2 </code></pre> <p>But all I have is all those variables empty! (I know I can put this code inside the GUI code, but that's not the real propouse because this simple m-File to sum will be much more complex, so I need the variables to go to a m-File).</p> <pre><code>Variavel_1 = [] Variavel_2 = [] Sum = [] </code></pre> <p>Can anyone understand why the global variables fails?</p> <p>Thanks in advance!</p>
