Hi,

could you help me please? This is me code:

   vd=size(UserData.info);
   for i= 0:vd(1)-4
     T = regexprep(cellstr(char(sym(UserData.matrix{4+i,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;

Code makes: if I write for example U1U2, than all numbers are subscript. But I need phi2U2, than everything after "phi" must be always subscript, so 2U2 must by subscript.

Thank you

It could be done, but with the requirement you have given, if you had something like

phi2u2+gamma8

then what you wrote would expect that {2u2+gamma8} would all be subscripted instead of just the 2u2 -- because you wrote that "everything after "phi" must always subscript" and the +gamma8 is "after "phi""
