MATLAB: Get variable from edittext

Question

Hey, basicly I made a gui with 3 inputtext fields and a button. When pressing the button it should put the data from the input field into a variable and then start a function with these variables. If i declare the variables with just a regular variable it seems to work.(see commented example) How do i read the edittext?

    % --- Executes on button press in pushbutton1.
    function pushbutton1_Callback(hObject, eventdata, handles)
    disp('start running code');
    handles = guidata(hObject);
    var1 = get(handles.edit1, 'string');
    var2 = get(handles.edit2, 'string');
    var3 = get(handles.edit3, 'string');
    %var1 = 2;
    %var2 = 0.5;
    %var3 = 300;
    freessimulatie(var1,var2,var3);

Answer 1

I fixed it.

I used this instead.

   edit1 = findobj(0, 'tag', 'edit1');
   var1 = str2double( get(edit1, 'string') );
   edit2 = findobj(0, 'tag', 'edit2');
   var2 = str2double( get(edit2, 'string') );
   edit3 = findobj(0, 'tag', 'edit3');
   var3 = str2double( get(edit3, 'string') );
