Matlab：如何检索标题，xlabel，ylabel和plotyy字体？(Matlab: how do I retrieve the title, the xlabel, the ylabel and font of a plotyy?)

 我有一些数据，我想改变它们： 
 
 
 
 标题 
 
 
 xlabel和ylabel（字体大小和内容） 
 
 
 刻度尺寸。 
 
 
 这就是我通常这样做的方式： 
 
title('new title ');
xlhand = get(gca,'xlabel');
set(xlhand,'string','xlabel','fontsize',13);
ylhand = get(gca,'ylabel');
set(ylhand,'string','ylabel','fontsize',13);
set(gca,'FontSize',13);
 
 它通常工作正常。 但是，当我想编辑使用ploty函数创建的绘图时，它不起作用。 唯一的影响是我的右ylabel改变了。 
 
 我知道，因为我现在有两个ylabels ，改变它们并不像普通情节那么容易。 但是，我很惊讶我无法更改x标签和标题。 这是为什么？ 
 
 上面的代码与plotxy函数有什么关系？ 我怎样才能使它工作？ 该文档不包含任何相关信息。 
 
 我正在使用Matlab R2015a。 
 
 编辑：是的，我的意思是情节 （我的问题中有一个错字）。 以下是文档中的示例代码： 
 
x = 0:0.01:20;
y1 = 200*exp(-0.05*x).*sin(x);
y2 = 0.8*exp(-0.5*x).*sin(10*x);

figure % new figure
plotyy(x,y1,x,y2) 

I have some figures, for which I want to change:
 
 
 
The title
 
 
The xlabel and the ylabel (both font size and content)
 
 
The ticks size.
 
 
This is how I usually do it:
 
title('new title ');
xlhand = get(gca,'xlabel');
set(xlhand,'string','xlabel','fontsize',13);
ylhand = get(gca,'ylabel');
set(ylhand,'string','ylabel','fontsize',13);
set(gca,'FontSize',13);
 
It usually works fine. However, it doesn't work when I want to edit a plot made with the ploty function. The only effect is that my right ylabel changes. 
 
I'm aware that since I have two ylabels now, changing them won't be as easy as for a normal plot. However, I'm surprised that I can't change the xlabels and the title. Why is that?
 
What's wrong with the above code in relation to the plotxy function? How can I make it work? The documentation doesn't contain any relevant information.
 
I'm using Matlab R2015a.
 
Edit: Yes, I meant plotyy (there was a typo in my question). Here is sample code from the documentation:
 
x = 0:0.01:20;
y1 = 200*exp(-0.05*x).*sin(x);
y2 = 0.8*exp(-0.5*x).*sin(10*x);

figure % new figure
plotyy(x,y1,x,y2)
