Function 使用GUI外函数更新GUI（MATLAB）

我正在尝试使用GUI之外的函数。这是一个.m文件，我想更新GUI组件handles.axes6和handles.axes7。以下是GUI m文件中的脚本

function pushbutton8_Callback(hObject, eventdata, handles)

h1 = handles.axes6; 
h2 = handles.axes7;

mousemotion(h1,h2);

功能代码（GUI外部）

函数（单击）
全球rdata；
nargin在GUI打开函数中，导出GUI句柄和轴句柄，然后从所需函数中获取它们，如下所示：

function figure_OpeningFcn(hObject, eventdata, handles,varargin)

%// This function has no output args, see OutputFcn.
%// hObject    handle to figure
%// eventdata  reserved - to be defined in a future version of MATLAB
%// handles    structure with handles and user data (see GUIDATA)
%// varargin   command line arguments to DatabaseViewerApp (see VARARGIN)

%// Choose default command line output for DatabaseViewerApp
handles.output = hObject;

%// Update handles structure
guidata(hObject, handles);
%// UIWAIT makes DatabaseViewerApp wait for user response (see UIRESUME)
%// uiwait(handles.mainFigure);

    %//set the current figure handle to main application data
    setappdata(0,'figureHandle',gcf);

    %//set the axes handle to figure's application data
    setappdata(gcf,'axesHandle1',handles.axes6);

    %//set the axes handle to figure's application data
    setappdata(gcf,'axesHandle2',handles.axes7);

end

function varargout = func1(varargin)

%// get the figure handle from the application main data
figureHandle = getappdata(0,'figureHandle');

%// get the axes handle from the figure data
axesHandle1 = getappdata(figureHandle,'axesHandle1');

%// get the axes handle from the figure data
axesHandle2 = getappdata(figureHandle,'axesHandle2');

%// And here you can write your own code using your axes

end

然后在任何函数func1中，按如下方式使用它们：

function figure_OpeningFcn(hObject, eventdata, handles,varargin)

%// This function has no output args, see OutputFcn.
%// hObject    handle to figure
%// eventdata  reserved - to be defined in a future version of MATLAB
%// handles    structure with handles and user data (see GUIDATA)
%// varargin   command line arguments to DatabaseViewerApp (see VARARGIN)

%// Choose default command line output for DatabaseViewerApp
handles.output = hObject;

%// Update handles structure
guidata(hObject, handles);
%// UIWAIT makes DatabaseViewerApp wait for user response (see UIRESUME)
%// uiwait(handles.mainFigure);

    %//set the current figure handle to main application data
    setappdata(0,'figureHandle',gcf);

    %//set the axes handle to figure's application data
    setappdata(gcf,'axesHandle1',handles.axes6);

    %//set the axes handle to figure's application data
    setappdata(gcf,'axesHandle2',handles.axes7);

end

function varargout = func1(varargin)

%// get the figure handle from the application main data
figureHandle = getappdata(0,'figureHandle');

%// get the axes handle from the figure data
axesHandle1 = getappdata(figureHandle,'axesHandle1');

%// get the axes handle from the figure data
axesHandle2 = getappdata(figureHandle,'axesHandle2');

%// And here you can write your own code using your axes

end

你还有问题吗？非常感谢你的帮助。但是如果我想链接这两个句柄并用它们代替gcf呢？有可能吗？我想同时设置两者。我不太了解您，但使用
setappdata（[handle]、“[any data name]、[any data value]），以及
[variable]=getappdata（[handle]，“[any data name]”）
要设置和获取信息，您可以为任何句柄设置信息，将应用程序数据作为信息存储库处理。我的两个句柄（handles.axes6和handles.axes7）用于两个3d轴。我需要一起旋转这两个轴。所以我想在我的外部函数中链接这两个句柄；通过将函数与axes事件链接，该函数不起作用，但是该函数应该在axes上应用一些处理，这非常简单，当您在axes6上执行任何操作时，只需在axes7上再次复制相同的代码即可
