How can I create this figure title in MATLAB?

问题:

I want to combine Latex, numbers, and Tex into the title of a figure using the following (beta_b and lambda are defined variables):

title(['$\overline{\beta}=$' num2str(beta_b) 'TE0 , \lambda=' num2str(lambda*1e6) ' \mum'], 'interpreter','latex'); 

But it doesn't display properly. What's the problem?

回答1:

You can't combine Latex and Tex in a title. You have to use one or the other (i.e. whichever one you set for the 'Interpreter' property). The following will work:

title(['$\overline{\beta}=$' num2str(beta_b) ...        ' TEO , $\lambda=$' num2str(lambda*1e6) ' $\mu$m'],...       'Interpreter','latex'); 

Note that you have to include $ on either side of \lambda and \mu so they can be interpreted properly. The $ also has to go between the \mu and m, otherwise it gets tripped up on the \mum.
