LaTex in Matlab legend
显示 更早的评论
I am trying to get my legend written in latex code, however I don't quite get most of the solutions I found when searching. My code is quite long, so I made a simplified version:
%
A= cos(tau)
l1 = sin(tau)
l2 = sin(tau + pi/8)
plot(tau, A, 'DisplayName', 'A(\tau)'), hold on
plot(tau, l1, 'HandleVisibility','off'), hold on
plot(tau, l2, 'DisplayName', 'l with $\eta_0 = \pi - \asin(\sqrt{K})$')
legend show
I have seen several solutions with legend(... 'interpreter', 'latex'), but I don't see how to incorporate that into my code. I have also seen some set(f,'defaulttextinterpreter','latex') but again I don't quite know how to use it and when I tried I only got an error.

This will call the LaTeX interpreter correctly:
A= cos(tau)
l1 = sin(tau)
l2 = sin(tau + pi/8)
plot(tau, A, 'DisplayName', '$A(\tau)$'), hold on
plot(tau, l1, 'HandleVisibility','off'), hold on
plot(tau, l2, 'DisplayName', 'l with $\eta_0 = \pi - \asin(\sqrt{K})$')
hl = legend('show');
set(hl, 'Interpreter','latex')
You have an LaTeX syntax error in the third plot call (for ‘l2’). I will defer to you to solve that.

Matlab understands all the basic functions that amsmath would load in a latex document. So you can use _, ^, as well as commands like \sin, \lim and \frac{}{}. Some more examples are included in the video https://www.youtube.com/watch?v=5TwChCWGllI , although the comments above cover you
