From: Luca Zanotti Fragonara on 22 Jul 2010 09:31 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}$$','interpreter','latex') > And I was also wondering, does latex interpreter has trouble with a > string as following: > > xlabel('\textbf\fontsize{', num2str(Char_Size) > ,'}\dot{\theta}','interpreter','latex') > > In the case I want to modify the fontsize of the string of xlabel? xlabel('$$\dot{\theta}$$','interpreter','latex','fontsize',20) -- Doug Schwarz dmschwarz&ieee,org Make obvious changes to get real email address.
