You can use √ to generate the symbol itself. However, you cannot create the overbar as far as I can tell. For example, this should in theory give the overbar but the renderer is too old to know about text-decoration
'<HTML>&radic;<span style="text-decoration:overline">Overline</span>'

Hi,
can you applies you idea in this code?
vd=size(UserData.info);
for i= 0:vd(1)-4
T = regexprep(cellstr(strcat(char('√'),'(omegat+','phi',char(symbol(1:coma-1)),')')), '([A-Za-z]+)(\d+)', '$1<FONT SIZE=-1>$2</FONT>');
T = regexprep(T, '(phi|alpha|beta|gamma|delta|epsilon|zeta|eta)', '&$1;');
result(4+i,1)=strcat('<HTML>',T);
end;

Dang, I keep forgetting that this forum renders HTML glyphs. The mark to use is
&radic;
Which point do you want the character to appear in the output?

Hi, if I use this code, then after √ is number 2 subscript. But this number should be normal. But other numbers should be subscripts...This is my code:
T = regexprep(cellstr(strcat('radic','2','(omegat+','phi',char(symbol(1:coma-1)),')')), '([A-Za-z]+)(\d+)', '$1<FONT SIZE=-1>$2</FONT>');

T = regexprep(cellstr(strcat('&radic;','2','(omegat+','phi',char(symbol(1:coma-1)),')')), '([A-Za-z]+)(\d+)', '$1<FONT SIZE=-1>$2</FONT>');
The √ will not be followed by a digit so it will not have the digit subscripted.

Sorry, but I got: &√;2U....
My code is:
T = regexprep(cellstr(strcat('&radic;','2','(omegat+','phi',char(symbol(1:coma-1)),')')), '([A-Za-z]+)(\d+)', '$1<FONT SIZE=-1>$2</FONT>');
T = regexprep(T, '(Alpha|Beta|Gamma|thetasym|piv|Delta|Epsilon|Zeta|Eta|Theta|Iota|Kappa|Lambda|Mu|Nu|Xi|Omicron|Pi|Rho|Sigmaf|Sigma|Tau|Upsilon|Phi|Chi|Psi|Omega|alpha|beta|gamma|delta|epsilon|zeta|eta|theta|iota|kappa)', '&$1;');
result(i,1)=strcat('<HTML>',T);
Can you help me please?

What did you adjust your code to be ?
(note: when you try to post '&radic;' here, change the & to &amp; or else it will get displayed as √
