请问一下，我想在gui编程中在自定义函数里改变axes控件属性，具体该如何操作？

function text_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
if strcmp(get(hObject,'Visible'),'off')
    axes(handles.Axes_Fig);
    surf(peaks);
end


function varargout = text_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;


function pushbutton1_Callback(hObject, eventdata, handles)
teare;


function teare
handles = guihandles(gcf);
Axes_Fig.XLim = [0.5 250.5];
Axes_Fig.YLim = [0.5 150.5];

类似这样 ，程序里面teare函数对于axes控件的设置无效，不晓得怎么回事
