Matlab GUI设计(2)

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)
[filename,pathname]=uiputfile({'*.bmp';},'保存图片','Undefined.bmp');
if ~isequal(filename,0)
    str = [pathname filename];
    px=getframe(handles.axes1);
    %saveas(gcf,str,'bmp');
    ta = getappdata(gcf,'Timg');
    imwrite(px.cdata,str,'bmp');
    close(gcf);
else
    disp('保存失败');
end;

（4）大小可调

% 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 new_pic_1 (see VARARGIN)

% Choose default command line output for new_pic_1
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes new_pic_1 wait for user response (see UIRESUME)
% uiwait(handles.figure1);
set(handles.axes1,'xtick',[]);%设置不显示x,y轴
set(handles.axes1,'ytick',[]);
set(handles.axes1,'ycolor','white');
set(handles.axes1,'xcolor','white');

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)||isequal(pathname,0)
    disp('Users Selected Canceled');
end
fpath=[pathname filename];
imgsrc = imread(fpath);
axes(handles.axes1);%axes1是坐标轴的标示
imshow(imgsrc);

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)
close(gcf)

(4)

function uibuttongroup1_SelectionChangedFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in uibuttongroup1
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global imgsrc
str=get(hObject,'String');
axes(handles.axes1);
switch str %调用三种边缘检测函数
    case '原图'
        imshow(imgsrc)
    case 'sobel'
        BW=edge(rgb2gray(imgsrc),'sobel');
        imshow(BW);
    case 'prewitt'
        BW=edge(rgb2gray(imgsrc),'prewitt');
        imshow(BW);
    case 'canny'
        BW=edge(rgb2gray(imgsrc),'canny');
        imshow(BW);
end

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)

13、

function varargout = pic_1(varargin)
% PIC_1 MATLAB code for pic_1.fig
%      PIC_1, by itself, creates a new PIC_1 or raises the existing
%      singleton*.
%
%      H = PIC_1 returns the handle to a new PIC_1 or the handle to
%      the existing singleton*.
%
%      PIC_1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in PIC_1.M with the given input arguments.
%
%      PIC_1('Property','Value',...) creates a new PIC_1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before pic_1_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop_music.  All inputs are passed to pic_1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
