Matlab界面设计的例子.doc

1、很简单，在界面上放三个单选按钮控制颜色（R、G、B），四个pushbutton（功能分别为绘制正弦、余弦、grid off、退出程序），可作为一个小小的入门。 程序为： %simpleGUI2.m-a simple use of Radiobutton and Pushbutton clear all; FigWin=figure(Position,[100,100,600,300],Name,Uicontrol:Push Button RadioButton,... NumberTitle,off); AxesHandle=axes(Position,[0.4,0.15,0.5,0.8],Box,on); ? RadioNum=3; for i=1:RadioNum Radio(i)=0;%initial value=0 end ? Radio(1)=uicontrol(FigWin,...%父对象FigWin（一figure对象），备注③ Style,Radio,... Position,[50 255 100 30],... String,Draw in Red,... CallBack,... [n=1;... if get(Radio(1),Value)==1;...%要使各radio button之间具有互斥性，要用if...else语句 set(Radio([1:(n-1),(n+1):RadioNum]),Value,0);... else;...%要加上分号，一种规定？参备注① set(Radio(1),Value,1);... end;... ColorStr=r;... set(FunHandle,Color,red)]);%曲线颜色根据radio button的选项实时变化，ColorStr是一个全局变量 ? Radio(2)=uicontrol(FigWin,... Style,Radio,... Position,[50 215 100 30],... String,Draw in Green,... CallBack,...
