Plot figure - get title

Hello,

I am reading the following code, and I do not understand the last two lines. I run it, but it does not change the figure. So I am quite confused what are the purpose of the these code lines?

Is there anyone having an idea? If so, could you kindly tell me?

Thanks a lot!

figure;
plot(xx,yy,'LineWidth',2);
axis([-1 1 -0.2 1.2] )
h = legend(['f*';'10';'Ch']);
v = get(h,'title'); % what is the purpose?
set(v,'string','Order');  % what is the purpose?

The purpose appears to be to set the 'title' property of the legend object to be 'Order'.

At least that what appears when I run this code:

xx = -1:0.1:1;
yy = xx.^2;

figure;
plot(xx,yy,'LineWidth',2);
axis([-1 1 -0.2 1.2] )
h = legend(['f*';'10';'Ch']);
v = get(h,'title'); % what is the purpose?
set(v,'string','Order');  % what is the purpose?

See the documentation section on Add Title to Legend (link) for details. Creating legend titles this way is relatively recent.
