function yesno = issymbolic(S)


try 
% Matlab cannot handle symbolic matrices of more than two
% dimensions correctly. We need to string S out first.
    S = double(simplify(S(:)));
    yesno = 0;
catch
% if S contains symbolic variables without numerical values,
% the conversion to "double" will fail. Then we end up here.
    yesno = 1;
end
