一个简单的Matlab_GUI编程实例

今天由于要帮一朋友用matlab处理一幅图片，处理图片的要求其实很简单，就是把图片加载进matlab中，然后显示出想要的某一列的趋势图来。

如果用代码写的话，程序如下：x=imread(‘文件路径\*.jpg’);figure(1);plot(x(:,100)); %假如要显示的是图像的第100列的趋势图显示效果如下图所示：虽然用Ｍ文件写两句很简单，不过带着感情，追求更好是我们永恒的动力，首先用Ｍ文件时候人机界面不友好，的看很多的代码，尤其对不太熟悉Ｍ编程的的人而言即使很简单也看着比较郁闷，因此我们接下来用matlab中的GUI来完成这个简单的例子，当然编程起来比这个复杂多，但是对使用者而言确很简单清楚。

这个就如同ＶＣ中的ＭＦＣ和ＷＩＮＤＯＷＳＦＯＲＭＳ一样。

做成的都是人机交互界面。

不废话了，看例子。

首先打开ＭＡＴＬＡＢ，要新建一个ＭＡＴＬＡＢ GUI 程序有三种方法，这里我直接在命令窗口里输入guide，新建一个空的ＧＵＩ程序，选择如下图：新建好的ＧＵＩ编程界面如下图，上面无非就是菜单，工具，还有编程用到的控件，还有编程的用户窗口。

这个和ＬＡＢＶＩＥＷ有点像。

不过ＬＡＢＶＩＥＷ的前面板都是用控件拖出来的，后面板也是拖控件画出来的。

而ＧＵＩ的显示界面是拖控件画出来的，其中一些属性参数要设置下，而后面的执行这些控件的都是写的Ｍ函数，即后面板都是要写代码的，这个比ＬＡＢＶＩＥＷ单纯的画程序要难，当然灵活性也大，不过个人感觉没一个简单的，都难呀。

至于上面控件的意思，怎么拖请自己看吧，若学过ＭＦＣ或者ＷＩＮＤＯＷＳＦＯＲＭＳ的人就会很容易理解的，这之间是太像了，呵呵。

我们的目的是显示图片，并且显示需要的某一列的趋势图。

为了使人机交互更好点，我们可以使加载图片时和我们选择打开文件夹那样完成，即自己选择路径，而不用每次在M文件里改路径。

还有我们要求在加载图片完成时立马显示出这幅图片的大小信息，即多少行，多少列。

第五章 Matlab 的GUI 程序设计Matlab 程序的用户界面，可以用图形句柄通过代码来制作，也可以用GUI(Graphic User Interface)编辑器来制作，或二者结合起来做。

我们分别用下面的例子来加以说明。

六、 用代码来制作GUI 界面例5.4对于传递函数为1212++=s s G ζ的归一化二阶系统，制作一个能绘制该系统单位阶跃响应的图形用户界面。

本例演示：（A ）图形界面的大致生成过程；（B ）静态文本和编辑框的生成；（C ）坐标网格控制键的形成；（D ）如何使用该界面。

（1）产生图形窗和轴位框：如图5-4所示。

图 5-4 产生坐标轴 clf reset%set(0,'DefaultFigureColor','b')H=axes ('unit','normalized','position',[0,0,1,1],'visible','off'); %建立轴,并取轴句柄Hset(gcf,'currentaxes',H); %在当前图形窗口上安置坐标轴Hstr='\fontname{隶书}归一化二阶系统的阶跃响应曲线';text(0.12,0.93,str,'fontsize',13); %在H上，相对于左下角的取值h_fig=get(H,'parent'); %取H的父句柄h_fig=gcfset(h_fig,'unit','normalized','position',[0.1,0.2,0.7,0.4]);%设置图形窗口h_fig的位置[0.1,0.2,0.7,0.4]（相对于屏幕）h_axes=axes('parent',h_fig,...'unit','normalized','position',[0.1,0.15,0.55,0.7],...'xlim',[0 15],'ylim',[0 1.8],'fontsize',8);%在H窗口上指定位置画新轴（2）在坐标框右侧生成作解释用的“静态文本”和可接收输入的“编辑框”：如图5-5所示。

MATLAB图像用户界面1、GUI入门示例（1）3种方式打开GUIDE开发环境：●在指令窗中运行guide指令。

●菜单：新建—>GUI。

●使用GUIDE按钮。

（2）使控件、组件图标带其名称一起显示，应采用以下步骤：●选择界面编辑器菜单项：File > Preference，引出GUIDE选项设置界面。

●勾选“show names in component palette”项。

（3）界面组件●GUI界面右下角“小黑块”，即“界面缩放句柄”●轴：点击“轴”图标，然后在工作区中的适当位置，拉出适当大小的“轴位框”，以供绘制响应曲线使用。

●静态文本框：；●可编辑文本框：；（4）界面组件参数的设置：●在”窗属性编辑器“设置：Resize on %图形窗是否可缩放Uints normalized %采用“归一化”单位计量窗口大小●“静态文本框”设置：FontUnits normalized %采用相对度量单位，缩放时保持字体比例FontSize 0.5 %字体大小String 归一化二阶系统的阶跃响应%Units normalized %采用相对度量单位，缩放时保持该区比例●轴：Box on %轴框封闭Units normalized %采用相对度量单位，缩放时保持比例XLim [0,15] %X轴范围YLim [0,2] %Y轴范围●可编辑文本框：FontUnits normalized %采用相对度量单位，缩放时保持字体比例FontSize 0.5 %字体大小String %删除缺省字符Units normalized %采用相对度量单位，缩放时保持该区比例（5）初步设计界面的保存在进行保存时，在指定的文件夹下会同时生成2个伴生文件ex0801.m和ex0801.fig。

(6)回调程序的编写Ex0801.m所包含的回调子函数函数体是空的。

插入下面代码：function edit1_Callback(hObject, eventdata, handles)% hObject handle to edit1 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA)% Hints: get(hObject,'String') returns contents of edit1 as text% str2double(get(hObject,'String')) returns contents of edit1 as a doubleget(hObject,'String'); %从编辑框读取输入字符zeta=str2double(get(hObject,'String')); %把字符转换成双精度数handles.t=0:0.05:15; %定义时间采样数组handles.y=step(tf(1,[1,2*zeta,1]),handles.t); %计算响应cla %清空坐标轴line(handles.t,handles.y) %在已有轴上绘制曲线。

matlab练习（创建GUI）matlab创建GUI⽅法1:使⽤GUIDE菜单式操作在matlab中输⼊guide，可以打开guide创建GUI的图形界⾯，按菜单操作即可注：matlab未来版本可能会取消掉这种⽅式⽅法2:编写代码创建GUI下⾯是⼀个简单的以代码⽅式创建GUI的例⼦，其中关键的⼀些点包括1. 创建⼀个figure object作为container2. 通过`uicontrol`创建container内的控件，通过`'Callback'`属性关联回调函数3. 回调函数参数⼀般是由两部分组成`(source,eventdata,handles)`，分别表⽰引起回调产⽣的控件的handle和(点击)事件的数据function simple_gui2% SIMPLE_GUI2 Select a data set from the pop-up menu, then% click one of the plot-type push buttons.

Read the pop-up menu Value property to% determine which item is currently displayed and make it the% current data. This callback automatically has access to% current_data because this function is nested at a lower level. function popup_menu_Callback(source,eventdata) % Determine the selected data set. str = source.String; val = source.Value; % Set current data to the selected data set. switch str{val}; case 'Peaks' % User selects Peaks. current_data = peaks_data; case 'Membrane' % User selects Membrane. current_data = membrane_data; case 'Sinc' % User selects Sinc. current_data = sinc_data; end end% Push button callbacks. Each callback plots current_data in the% specified plot type. function surfbutton_Callback(source,eventdata) % Display surf plot of the currently selected data. surf(current_data); end function meshbutton_Callback(source,eventdata) % Display mesh plot of the currently selected data. mesh(current_data); end function contourbutton_Callback(source,eventdata) % Display contour plot of the currently selected data. contour(current_data); endendGUI展⽰⽅法3:利⽤AppDesigner和⽅法⼀的Guide类似总结我们有三种不同⽅式在matlab中创建简单的GUI程序，其中⽐较推荐的是使⽤编程的⽅式。

matlab gui 实例以下是一个简单的Matlab GUI实例，用于计算两个数的平均值：```matlabfunction myGUI% 创建主窗口fig = uifigure('Name', '计算平均值', 'Position', [100 100 300 200]);% 创建两个输入框和按钮input1 = uieditfield(fig, 'numeric', 'Position', [20 150 100 30]);input2 = uieditfield(fig, 'numeric', 'Position', [180 150 100 30]);button = uibutton(fig, 'Position', [120 100 60 30],'Text', '计算');% 添加按钮的回调函数button.ButtonPushedFcn = @(src,event)calculateAverage(src, input1, input2);end% 计算平均值的函数function calculateAverage(src, input1, input2)% 获取输入框的值num1 = input1.Value;num2 = input2.Value;% 计算平均值average = (num1 + num2) / 2;% 显示结果对话框uialert(src.Parent, sprintf('平均值为：%g', average), '结果', 'Icon', 'info');end```你可以将以上代码保存为一个.m文件，然后在Matlab命令窗口中运行`myGUI`函数，即可启动GUI应用程序。

题目要求:在窗口中添加“按钮”控件和“文本”控件，在按下按钮时，文本控件显示“this is my work”
1.在command widows中输入guide,调出guide控制窗口
2.在出现的窗口中新建一个空白的GUI，即BLANK GUI
3.拖入push button 控件和Edit Text 控件
4.设置Edit Text的属性string改成空白，style改成text, tag改为txthello
这是要注意tag是句柄的意思，句柄是编写程序时要用到的，看后边就知道了
5.保存文件，注意这里一定要先保存，文件名取为“c2figu1”保存之后才会有属性栏中callback 的变化
上图是没有保存时的callback
上图是保存后的callback
保存后弹出一个M文件编辑窗口，如下图。

注意这个窗口中的内容都是不可删除的。

6．在此M文件窗口中找到此段话：
在它的下边写入这段话：
set(handles.txthello,'string','this is my work');
然后保存
7.在command windows中输入文件名：c2figu1
出现如下窗口：
点击push botton,出现这样的情况:
OK！演示完成。

实验名称： Matlab GUI设计一、实验题目：自行设计一个GUI界面，在界面中描绘函数的图像。

基本要求：1）可以通过按钮，动态让该图像旋转起来2）可以通过输入文本框，控制该图像旋转的时间二、实验内容描绘函数：x=-10:0.1:10;y=-10:0.1:10;[xx,yy]=meshgrid(x,y);zz=sin(sqrt(xx.*xx.*xx+yy.*yy)).\sqrt(xx.*xx.*xx+yy.*yy); plot3(xx,yy,zz);旋转函数（1）：axis vis3dshading facetedfor i=1:36camorbit(10,0,'camera')M=getframe(gcf);End旋转函数（2）：for i=1:36camorbit(10,0)drawnowend控制时间函数：a=get(handles.txt,'String');t=2.*str2double(a);按钮修饰函数：I=imread('1.jpg');set(handles.pushbutton1,'cdata',I);I=imread('1.jpg');set(handles.pushbutton2,'cdata',I);附加功能（输出gif文件，可用于ppt）nn=frame2im(M);[nn,cm]=rgb2ind(nn,256);if i==1imwrite(nn,cm,'out.gif','gif','LoopCount',inf,'DelayTime',0.1);elseimwrite(nn,cm,‘out.gif’,‘gif’,‘WriteMode’,‘append’,‘DelayTime’,0.1); endGUI设计界面：三、实验分工：负责旋转函数，描绘函数，输出gif文件函数及GUI界面的设计执行，编写整理实验报告。

matlab gui界面设计实例
以下是一个简单的MATLAB GUI界面设计实例：
1. 打开MATLAB软件并创建一个新的GUI文件，首先需要添加一个静态文本标签来说明该程序的用途。

2. 在接下来的步骤中，我们将添加一个单选按钮和一组复选框，允许用户选择他们的喜好和选项。

3. 其他元素可添加日期选择器，文本框和按钮等等。

4. 最后，我们需要添加一个事件处理程序，以便处理用户点击“提交”按钮时的操作。

通过这样一个简单的实例，我们可以学习到MATLAB GUI界面的基本设计原则和步骤，以及如何处理用户交互事件并使用MATLAB功能实现功能。

基于MATLAB-GUI的简单计算器设计题目：计算器完成一个简单的计算器。

要求（但不限于）：GUI上具有数字键盘输入区域，能够进行加、减、乘、除、三角函数等基础运算。

界面简洁、美观可能需要的控件：Push ButtonEdit TextPop-up Menu1 功能介绍本程序是一个简单的计算器程序，使用MATLAB软件编写完成。

主要具有加、减、乘、除、三角函数等基础运算，并通过GUI进行程序使用的交互。

程序交互界面如下：图1 程序的交互界面2 功能实现首先用MATLAB GUI功能，在绘制一个动态文本框和一个文本编辑框，以及25个命令按钮，调整好各控件大小、颜色，整体布局如图所示：备注：软件版本：MATLAB R2011b2.1 布局GUI1、打开MATLAB，在Guide中新建FIG文件2、然后双击“Blank GUI(Default)”或单击OK键出现GUI窗口3、添加按钮和动态文本框4、根据按钮的作用及视觉效果做一定的修改对按钮的字符串大小、颜色进行设置，对按钮的位置进行排布，尽量使按钮集中在动态文本框下面。

最终设置的动态文本框为灰色，其他按钮均为蓝色。

5、保存、添加功能函数将做好的按钮及动态文本框保存后自动弹出Editor的M文本，然后对相应的pushbutton添加功能函数。

以下是相应按钮的功能函数。

（1）数字按键编写。

在function pushbutton1_Callback(hObject, eventdata, handles）下输入：global jja=get(handles.edit1,'String');if(strcmp(a,'0.')==1)&&(jj==0)set(handles.edit1,'String','0.')elsea=strcat(a,'0')set(handles.edit1,'String',a)endjj=0这是使用句柄handles指向对象edit1，并以字符串形式来存储数据文本框edit1的内容，并存储数个“0”，然后由set(handles.edit1,'String',a)在edit1中输出。
