Matlab如何画双纵坐标图

简介用Matlab画图时，需要用双纵坐标轴时，用什么命令来实现呢，给大家分享下面的例子。方法程序%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%clf;dx=0.1;x=0:dx:4;y=x.*sin(x);s=cumtrapz(y)*dx;a=plotyy(x,y,x,s,'stem','plot');text(0.5,1.5,'ontsize{14}ity=xsinx')sint='{ontsize{16}int_{ontsize{8}0}^{x}}';ss=['ontsize{14}its=',sint,'ontsize{14}itxsinxdx'];text(2.5,3.5,ss)set(get(a(1),'Ylabel'),'String','被积函数ity=xsinx')set(get(a(2),'Ylabel'),'String',ss)xlabel('x')%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%绘制的图像如下图所示：
