11、
（1）界面设计
（2）添加按钮的回调函数
function pushbutton1_Callback(hObject, eventdata, handles) % hObject handle to pushbutton1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) fd=get(handles.edit1,\'String\');%获取函数 axes(handles.axes1)%坐标轴 Xmin=get(handles.edit4,\'String\'); Xmax=get(handles.edit5,\'String\'); Ymin=get(handles.edit6,\'String\'); Ymax=get(handles.edit7,\'String\');%坐标轴范围 f=ezplot(fd,[str2num(Xmin),str2num(Xmax),str2num(Ymin),str2num(Ymax)]);%注意转成数字 col=get(handles.edit2,\'String\');%获取输入的颜色 wid=get(handles.edit3,\'String\');%获取输入的线宽 set(f,\'Color\',col);%设置颜色 set(f,\'Linewidth\',str2num(wid));%注意str2num grid on

12、图片打开与保存
(1)前台界面
(2)添加打开图片的回调函数
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[filename,pathname]=uigetfile({\'*.jpg\';\'*.bmp\';\'*.gif\'},\'选择图片\');
if isequal(filename,0)
disp(\'Users Selected Canceled\');
else
str=[pathname filename];
im = imread(str);
axes(handles.axes1);%axes1是坐标轴的标示
imshow(im);
end;
（3）保存并退出的回调函数
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

%saveas(gcf,str,\'bmp\');
ta = getappdata(gcf,\'Timg\');
imwrite(px.cdata,str,\'bmp\');
close(gcf);
else

12、参数传递
（1）
clear all hfig=figure; %新建一个figure窗体 setappdata(hfig,\'url\',\'http://www.matlabsky.com\'); %添加应用程序数据url setappdata(hfig,\'author\',\'baby_wolf\'); %添加应用程序数据author getappdata(hfig,\'url\')%获取应用程序数据 getappdata(hfig)

% PIC_1, by itself, creates a new PIC_1 or raises the existing
% singleton*.

% the existing singleton*.
%

% function named CALLBACK in PIC_1.M with the given input arguments.

% stop_music. All inputs are passed to pic_1_OpeningFcn via varargin.
