Hi, I try to display a string containing some characters that are underlined or with a hat? Does someone know how to proceed? Thanks

What does "display" exactly mean? Where? In the command window, a title of an AXES, inside a button or in the name of a figure?

In text(), title(), etc. Now I have the solution to get the underline but not for the bar. Thanks

If you use text(), title(), xlabel(), etc. you can use latex which is the default interpreter.
https://en.wikipedia.org/wiki/LaTeX
% title('S\underline{tring} now x hat:\hat{x}', 'FontSize', 30, 'Interpreter', 'latex')
title('S\underline{tring}', 'FontSize', 30, 'Interpreter', 'latex')
I couldn't get the hat to work, but the underline worked. MATLAB admits they don't support all LATEX instructions - maybe hat is one of those.

Thank you very much, the underline works indeed. Do you have a solution for the bar (a dash over a character, to replace the hat)? Thanks

Ran in:
You can use \bar or \overline - the length of the dash is different.
text(0.5, 0.5, 'This is a bar over x - $\bar{x}$', 'Interpreter', 'latex')
figure
text(0.5, 0.5, 'This is a bar over x - $\overline{x}$', 'Interpreter', 'latex')
