一个GUI例子。包括绝大部分GUI操作

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

%-----全局变量说明------------------------------------------------------------------------------------------
% no 当前第几道题
% A:part 1   的参数读取矩阵
% B：part 2  的参数读取矩阵
% C：part 3  的参数读取矩阵
% D:一个只由0和1组成的向量，决定左右按钮顺序或颠倒
% PART：表示当前在进行哪个部分 1 2 3

str1=num2str(no);                 %这两行显示题号，从全局变量no获得数据
set(handles.edit1,'String',str1);


D=randi([0 1],280,1);%生成一个1*72 一维序列a，a是只有0，1组成，长度72的radom序列 用于决定音频1音频2随机是原声和合成声


N=280;                             %输入需要抽取的原始音频的数量  
num=380;                           %音频库里面音频总数量  
p=randperm(num);                  %随机生成1~num个随机整数


a=p(1:N);                         %取p的前N个数  a是一个单行矩阵
%----------------------------------------------------------------%A矩阵是3*72，每一行从左到右是，NV通道数，vC载波类型（1-tone,2-noise），o处理策略（1-ACE,2-CLA）
