Set title in two lines with different font sizes with interpreter latex

It is possible to set title in two lines with different font sizes with interpreter latex?

i found an answer how to do that BUT with interpreter tex. for example:

title(['\fontsize{20} Thermometer output signal' char(10) ...
    '\fontsize{10} Look small' char(10) ...
    '\fontsize{20} Mixed_{\fontsize{8} underscore}'],'interpreter','tex');

this is mine without different font sizes:

TT=title({'$Thermometer\quad output\quad signal$','$EXP02$'},'FontWeight','bold',...
    'Interpreter','latex');

thanks

title(['\fontsize{12}{0}\selectfont$Large$', char(10), ...
       '\fontsize{8}{0}\selectfont$small$'], ...
       'interpreter','latex');

Written by @jose herrero: Hi Jan, thanks for your simple code. Very usefull to plot stationary titles in 2 lines. Can you also feed strings that change (e.g., numer of trials)?

Str =10;
charnow = ['#Trials: aS=' num2str(Str)
title(['\fontsize{12}{0}\selectfont$ITPC @ 40hz$', char(10), ...
'\fontsize{8}{0}\selectfont$"charnow"$'], ...
'interpreter','latex');

thanks,

@jose herrero: Yes, this works also:

Str =10;
charnow = sprintf('#Trials: aS=%f', Str);  % More direct than NUM2STR
title(['\fontsize{12}{0}\selectfont$ITPC @ 40hz$', char(10), ...
       '\fontsize{8}{0}\selectfont$', charnow, '$'], ...
       'interpreter','latex');

very useful Jan, thanks! For me (2019b) it works better using num2str.

Using 'sprintf', it adds some extra characters (e.g, 'Font').

Quick questions: is it also possible to have all in 1 single line (instead of 2) but with different fonts? where do you select the font type in your function?

Str=10;Vtr=20;Btr=30;

charnow = ['Trials (aS=' num2str(Str) ',aV=' num2str(Vtr) ',aB=' num2str(Btr) ')'];

title(['\fontsize{12}{0}\selectfont$ITPC @ Visfreq$', char(10), ...

'\fontsize{8}{0}\selectfont$', charnow, '$'], ...

'interpreter','latex');

@jose herrero: Simply try it. Omit the char(10) and all appears in 1 line. Omit other parts as "\selectfont$small$" and see, what happens. You cannot damage anything so feel free to experiment.
