Hello,

I am trying to show in the xlabel of a graph the symbol of derivative over a greek letter, and I receive the error described in the subject.
Here it is my code:

xlabel('\textbf\dot{\theta}','interpreter','latex')

or

xlabel('\bf\dot{\theta}','interpreter','latex')

They don't work.

Is there a problem with the \dot command?

And I was also wondering, does latex interpreter has trouble with a string as following:

xlabel('\textbf\fontsize{', num2str(Char_Size) ,'}\dot{\theta}','interpreter','latex')

In the case I want to modify the fontsize of the string of xlabel?

You need to use math mode ($$). Also, I don't think a bold version of
\theta exists so I would do this:

xlabel('$$\dot{\theta}$$','interpreter','latex')

xlabel('$$\dot{\theta}$$','interpreter','latex','fontsize',20)
