Matlab:uiopen"使用handle.handle / get时出错无效或删除对象。"

我是一名具有先前编程经验的Matlab初学者,并制作了一个生成和绘制数据的GUI。作为GUI的一部分,我希望能够保存和加载数据,因此创建了以下工具栏项回调:

function save_ClickedCallback(hObject, eventdata, handles)

uisave('handles');

.......

function open_ClickedCallback(hObject, eventdata, handles)

uiopen('*.mat');

guidata(hObject, handles);

updatePlot(handles); %updates the GUI's plots

set(handles.opt,'Value',handles.optValue); %updates some displayed parameters

set(handles.nsimu,'String',handles.nsimuString); %updates some displayed parameters

如果我在同一会话期间保存并加载数据,一切正常,但如果我尝试在新会话中加载数据,则会出现以下错误:

Error using handle.handle/get

Invalid or deleted object.

Error in MonteCarloKAGRA_GUI>updatePlot (line 79)

subplot(get(handles.noise, 'Value')+get(handles.convergence, 'Value')+1,1,1,'Parent',handles.plotArea);

Error in MonteCarloKAGRA_GUI>open_ClickedCallback (line 485)

updatePlot(handles);

Error in gui_mainfcn (line 96)

        feval(varargin{:});

Error in MonteCarloKAGRA_GUI (line 42)

    gui_mainfcn(gui_State, varargin{:});

Error in
@(hObject,eventdata)MonteCarloKAGRA_GUI('open_ClickedCallback',hObject,eventdata,guidata(hObject))


Error while evaluating uipushtool ClickedCallback

此外,GUI的一般使用似乎已经崩溃,例如,单击生成数据按钮会出现错误:

Error using handle.handle/get

Invalid or deleted object.

Error in MonteCarloKAGRA_GUI>generate_Callback (line 213)

str=get(handles.opt,'String');

Error in gui_mainfcn (line 96)

        feval(varargin{:});

Error in MonteCarloKAGRA_GUI (line 42)

    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)MonteCarloKAGRA_GUI('generate_Callback',hObject,eventdata,guidata(hObject))


Error while evaluating uicontrol Callback

非常感谢任何帮助!
