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.
