% 使用plotyy函数绘制双坐标轴图像

x2=-2.9:0.02:2.9;
y2=sin(3*x2);

% 通过句柄函数改变属性
% 添加纵坐标轴名称

% Use the xlabel and title commands to label the x-axis and add a title: 
% xlabel('Zero to 20 \musec.')
% title('Labeling plotyy')

% Use the line handles to set the LineStyle properties of the left- and right-side plots: 
% set(H1,'LineStyle','--')
% set(H2,'LineStyle',':
