matlabGUIの別の関数のある関数の変数の値にアクセスしたい。例えば

    % --- Executes on button press in browseCoverHide.
function browseCoverHide_Callback(hObject, eventdata, handles)
  % hObject    handle to browseCoverHide (see GCBO)
  % eventdata  reserved - to be defined in a future version of MATLAB
  % handles    structure with handles and user data (see GUIDATA)
[File,Path] = uigetfile('*.png','Select Image');
path = strcat(Path,File);
global covImg
covImg = imread(path);
axes(handles.axes1);
imshow(covImg);

     % --- Executes on button press in browseSecImg.
function browseSecImg_Callback(hObject, eventdata, handles)
  % hObject    handle to browseSecImg (see GCBO)
  % eventdata  reserved - to be defined in a future version of MATLAB
  % handles    structure with handles and user data (see GUIDATA)
global covImg
axes(handles.axes3);
imshow(covImg);

ここからアクセスCovImgしたいのですが、動作しません。function browseSecImg_Callbackfunction browseCoverHide_Callback

グローバルを使用する必要はありません。handlesの標準的な方法である変数を使用してデータを転送できますGUIDE。

imshow(handles.covImg);
guidata(hObject,handles);
