I would like to change the figure xlabel as 'I want to use \varepsilon_a', but \varepsilon cannot be recognized in my 2019b version Matlab (but \epsilon can). Any suggestions to realize this?

Thanks, but then I cannot use subscript here, right? Also, I need a sentense within which there is an \varepsilon, I tried:

xlabel('Other part of the sentense', (char(949)))

it also dosen't work

Dear H LIU,

You need to type like this:

xlabel(['{Other part of the sentense}' char(949)])

Further, if you want using suberscript above (^) or below (_) you can add them like this:

xlabel(['{Other part of the sentense}^' char(949)]) % suberscript above \varepsilon
%or
xlabel(['{Other part of the sentense}_' char(949)]) % suberscript below \varepsilon

Best Regards,
