《MATLAB 7.0编程基础》第7章 （源码实例）主要讲解MATLAB句柄图形对象

figure(1);
plot(peaks);
text(20,6,'Peaks')
title('属性设置前');
figure(2);
plot(peaks);
set(findobj('Type','line'),'Color','k')
h1=text(20,6,'Peaks');
h2=findobj('Type','line');
h3=title('属性设置后');
%获取对象句柄
PropName(1) = {'BackgroundColor'};
PropName(2) = {'Marker'};
PropName(3) = {'FontName'};
%对象的属性名元胞
PropVal(1) = {[.7 .9 .7]}; 
PropVal(2) = {'.'}; 
PropVal(3) = {'隶书'};
%对象的属性
set(h2,PropName(2),PropVal(2))
set([h1 h3],[PropName(1) PropName(3)],[PropVal(1) PropVal(3)])
