目标：根据自己写的函数，写一个交互式界面。
其实整体较简单，关键是理解整个MATLAB GUI 运行的逻辑！
PS 一切将简单问题复杂化的东西，真的可恨！
第一步：命令窗口输入guide，得到 “.fig” 和 “.m” 文件
第二步：设计界面
第三步：编写界面中元素对应代码
上述界面框对应的代码如下：
%%%%%%%%%%%%%%%%%%%%%%%%%%% 主函数 %%%%%%%%%%%%%%%%%%%%%%%%%%function varargout = Example_test(varargin)% EXAMPLE_TEST MATLAB code for Example_test.fig%EXAMPLE_TEST, by itself, creates a new EXAMPLE_TEST or raises the existing%singleton*.%%H = EXAMPLE_TEST returns the handle to a new EXAMPLE_TEST or the handle to%the existing singleton*.%%EXAMPLE_TEST('CALLBACK',hObject,eventData,handles,...) calls the local%function named CALLBACK in EXAMPLE_TEST.M with the given input arguments.%%EXAMPLE_TEST('Property','Value',...) creates a new EXAMPLE_TEST or raises the%existing singleton*. Starting from the left, property value pairs are%applied to the GUI before Example_test_OpeningFcn gets called. An%unrecognized property name or invalid value makes property application%stop. All inputs are passed to Example_test_OpeningFcn via varargin.%%*See GUI Options on GUIDE's Tools menu.

% 行向量！set(handles.edit2,'String',C)
主要注意如下几点：
（1）核心是写“按钮”和“可编辑文档”对应的callback部分，其他（如主函数，opening function, output function）不需要动！
（2）了解不同子函数间数据是如何传递的，本文中采用的代码如下，其他方式详见Matlab的GUI参数传递方式总结。
data=importdata(file);handles.data=data; % 不同子函数之间进行数据传输guidata(hObject,handles) % 在子函数最后，一定要加上这句！
（3）如何画图，本文采用的代码如下：
axes(handles.axes1);plot(data,'k','linewidth',1,'Color',[0.7 0.7 0.7]);
（4）如何清空图形和“可编辑文本”内的文字，代码如下
function pushbutton3_Callback(hObject, eventdata, handles)% hObject handle to pushbutton3 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA)trydelete(allchild(handles.axes1));endset(handles.edit1,'String','');
（5）理解“get函数”和“set函数”在GUI中的意义！
（6）一个文本框内放入向量，思路是将向量变成字符串，注意得是行向量！
S=data(1:2,1);C=num2str(S'); % 行向量！set(handles.edit2,'String',C)
