在MATLAB中在函数和回调之间传递数据(Passing data between functions and callbacks in MATLAB)

 我是MATLAB GUI构建的新手，我正在尝试学习如何在两个GUI之间传递数据。 我的问题是如何从子GUI调用主GUI中的函数。 
 
 例如： 
 
 在主GUI中，我从各自的回调中获取两个文本框中的值： 
 
handles.A= str2double(get(handles.textbox1,'string'));  

guidata(hObject,handles)

handles.B = str2double(get(handles.textbox2,'string'));   

guidata(hObject, handles)
 
 那么除了上面的内容之外，我还有第三个功能就是这样做： 
 
function addition(handles)    

C= handles.A + handles.B
 
 然而，第三个功能是通过按钮按钮从子GUI访问，如下所示： 
 
function pushbutton1_Callback(hObject, eventdata, handles)   

main_gui('addition');
 
 我得到的错误是没有足够的输入参数在C = handles.A + handles.B ，但我不知道为什么我收到此错误。 谁能帮我？ 

I am new to MATLAB GUI building and I am trying to learn how to pass data between two GUIs. My question is how to call a function in the main GUI from a sub GUI.
 
For example:
 
In the main GUI, I am getting the values from two text box from their respective callbacks as such:
 
handles.A= str2double(get(handles.textbox1,'string'));  

guidata(hObject,handles)

handles.B = str2double(get(handles.textbox2,'string'));   

guidata(hObject, handles)
 
then in addition to the above, I have a third function that does addition as such:
 
function addition(handles)    

C= handles.A + handles.B
 
The third function however is being accessed from the sub GUI through a button push as follows:
 
function pushbutton1_Callback(hObject, eventdata, handles)   

main_gui('addition');
 
The error I am getting is not enough input arguments in the line C = handles.A + handles.B, but I don't know why I am getting this error. Can anyone help me?
