How to put a hat on letters in a legend?

Hey everyone,

I am trying to create a legend for one of my graphs that contains two entries: p and p^^CS - I want a hat on the p and I also want CS in the index....

Can someone tell me how to do that??

Thanks a lot!

You should use the LaTeX interpreter:

legend({'$\hat{p}^{CS}$'},'Interpreter','latex')

I used the following command now:

 legend({'p','$\hat{p}^{CS}$'})

 set(legend,'Interpreter','latex')

Both legend entrees are in a different style now though... how can I change that?

[Zoltán Csáti]

By example:

p = plot(1,2,'O');
hold on
pCS = plot(1,3,'rO');
leg = legend({'p';'$\hat{p}^{CS}$'});
set(leg,'Interpreter','latex');

Now you get the same format. However it seems that the hat changed its style. It is definitely because of it, since after

plot('1,2,'o');
legend({'p'},'Interpreter', 'latex');

results the same style for p.

It turns out to be generally difficult in LaTeX to create upright symbols or modified alphabets (such as hat modifier). The easy methods that remove the italics in math mode, do not apply to symbols.

The LaTeX solution to this involves using the amsmath package (in particular amstext). Unfortunately, MATLAB does not currently provide any method for importing the amsmath package.

set(legend( '$$|\hat{u}_1|/|\hat{u}_{max}|$$', '$$|\hat{v}_1|/|\hat{u}_{max}|$$'),'Interpreter','Latex','FontSize', 10);
