M = [3,0,0;1,2,0;0,0,3];
L = {'A','B','C'};
X = [L(:),num2cell(M,2)]';
fprintf('    %3s %3s %3s\n',L{:})
fprintf('%3s %3d %3d %3d\n',X{:})

prints this:

      A   B   C
  A   3   0   0
  B   1   2   0
  C   0   0   3

You can adjust the spacing to suit your data and strings by changing the field width of the conversion operators.
