Using epsilon in legend

I want to use Greek symbol epsilon "ɛ" in my legend and I use \epsilon. But it gives me "є" . I found a solution using char(949). But I can not use subscript with that. Actually I need to write "ɛ_21". Can anyone please help me?

You just need to concatenate the special character with the subscript, and it works (at least in R2015b):

figure(1)
plot(1:10,  rand(1,10))
legend([char(949) '_{21}'])

What if you what \varepsilon in the middle of a title? is that possible? Something like this?

title('\sigma_{longitudinal} - '[char(949) '_{longitudinal}'],'FontSize',14)

I'm not a fan of using 'Intepreter','LaTex' because it changes the font, so I'm curious if there is another way. Thank you!

Try this:

title(' $\varepsilon_{21}$ ','interpreter','latex')

[Chad Greene]

Ah, you said legend. There's an extra step for legends:

l = legend('$\varepsilon_{21}$'); 
set(l,'interpreter','latex')

Thanks Chad. It also works!

I have a new question in this topic I need to put ɛ' and ɛ'' in two different graphs

I have tried [char(949) ' ' '] or [char(949) ' " ']

I have also tried with \varepsilon but it does not seem to work. Can somebody help me?

You just change the interpreter to latex in any function you need (like title, ylabel, legend, etc.) and you can use both epsilons variations.

plot(rand(100, 1))
title('$\epsilon$  and  $\varepsilon$', 'Interpreter','latex')
