如何在MATLAB中创建该图形标题？

Question

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?

Answer 1

You can't combine Latex and Tex in a title . You have to use one or the other (ie 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 .
