This comment describes that mechanism.%|%| Each callback subfunction declaration has the following form:%| <SUBFUNCTION_NAME>(H, EVENTDATA, HANDLES, VARARGIN)%|%| The subfunction name is composed using the object's Tag and the %| callback type separated by '_', e.g. 'slider2_Callback',%| 'figure1_CloseRequestFcn', 'axis1_ButtondownFcn'.%|%| H is the callback object's handle (obtained using GCBO).%|%| EVENTDATA is empty, but reserved for future use.%|%| HANDLES is a structure containing handles of components in GUI using%| tags as fieldnames, e.g. handles.figure1, handles.slider2. This%| structure is created at GUI startup using GUIHANDLES and stored in%| the figure's application data using GUIDATA. A copy of the structure%| is passed to each callback.  You can store additional information in%| this structure at GUI startup, and you can change the structure%| during callbacks.  Call guidata(h, handles) after changing your%| copy to replace the stored original so that subsequent callbacks see%| the updates. Type "help guihandles" and "help guidata" for more%| information.%|%| VARARGIN contains any extra arguments you have passed to the%| callback. Specify the extra arguments by editing the callback%| property in the inspector. By default, GUIDE sets the property to:%| <MFILENAME>('<SUBFUNCTION_NAME>', gcbo, [], guidata(gcbo))%| Add any extra arguments after the last argument, before the final%| closing parenthesis.% --------------------------------------------------------------------function varargout = btnDraw_Callback(h, eventdata, handles, varargin)try   str=get(handles.strB,'String'); str0=[];   for i=1:size(str,1) % 將所有輸入的字符串串接起來      str0=[str0, deblank(str(i,:))];   end       eval(str0); % 對字符串求值，   axes(handles.myAxes); % 將坐標系設置為當前坐標系   surf(x,y,z); % 繪制三維圖catch   errordlg('數據有問題，請檢查'); % 如果上述程序出錯，則顯示錯誤信息end% --------------------------------------------------------------------function varargout = btnDemo_Callback(h, eventdata, handles, varargin)str1='[x,y]=meshgrid(-3:0.1:3, -2:0.1:2);';str2='z=(x.^2-2*x).*exp(-x.^2-y.^2-x.*y);';set(handles.strB,'String',str2mat(str1,str2));btnDraw_Callback(h, eventdata, handles, varargin)% --------------------------------------------------------------------function varargout = edXPos_Callback(h, eventdata, handles, varargin)try   xx=eval(get(handles.edXPos,'String')); % 讀取光源位置    yy=eval(get(handles.edYPos,'String'));    zz=eval(get(handles.edZPos,'String'));    axes(handles.myAxes); % 將坐標系設置為當前坐標系   light('Position',[xx,yy,zz]); % 設置光源catch   errordlg('數據有問題，請檢查'); % 如果上述程序出錯，則顯示錯誤信息end% --------------------------------------------------------------------function varargout = chkX_Callback(h, eventdata, handles, varargin)xx=get(handles.chkX,'Value'); % 讀取是否要網格標志yy=get(handles.chkY,'Value'); zz=get(handles.chkZ,'Value'); set(handles.myAxes,'XGrid',xx,'YGrid',yy,'ZGrid',zz)function out=onoff(in) % 將 0,1 轉換成 off, onout='off'; if in==1, out='on'; end% --------------------------------------------------------------------function varargout = lstColor_Callback(h, eventdata, handles, varargin)v=get(handles.lstColor,'Value'); % 得出列表框的選項axes(handles.myAxes); % 將坐標系設置為當前坐標系switch vcase 1, shading flat; case 2, shading interp;case {3,4}, shading faceted;end
