How to add hat symbol to "xtick"

Hi there, I want to add a hat to my xtick:

xticks([B_hat(3),B_hat(2), B_hat(1)])
xticklabels({'\hat B_H' 'B_M' 'B_L'})

I've tried

yticklabels({'V_U'},'Interpreter', 'latex');

or codes like:

set(Figure1,'defaulttextinterpreter','latex');

Both do not work. Anyone has an idea? Thank you!

Have to escape LaTex sequences with "$$" before and after...try something like

hAx=axes;
xlim([1 3]); xticks([1:3])   % a sample axes object
lbls=['A':'C'].';            % wanted text labels to apply
fmt='$$\\hat{%c}$$';         % formatting for the carat 
txt=arrayfun(@(s) sprintf(fmt,s),lbls,'UniformOutput',false); % generate the labels
hAx.TickLabelInterpreter='latex';
hAx.XTickLabel=txt;          % and apply them...

Salt to suit...

Thank you a lot! And I also figure out that I can add text to the graph, this makes things easier.

Glad to help...and good luck w/ LaTeX syntax--it's even worse than regular expressions trying to figure out what will/won't work in the MATLAB implementation.

If this solves the problem, how about ACCEPT the answer so others will know is a solution...
