Thanks! this is really an easy approach. I defined Ang as you suggested and then concatenated that variable in a label. Maybe someone would find helpful this example
Ang = char(197); xlabel(['Pore width (' Ang ')'])

Probably the easiest way is to define it as:
Ang = char(197);
To produce a cell string for your legend, this works:
lgndstr = regexp(sprintf('%d%c ', [[1:3]', ones(3,1)*197]'), ' ', 'split');
legend(lgndstr(1:end-1))
producing:
'1Å' '2Å' '3Å'
The alternative is to use a LaTeX string and specify the 'latex' interpreter.
