How can put eigenvalues in ascending order?

Hi,

I am using something like [V,D] = eig(S) and I would like the eigenvalues in ascending order in the diagonal. V, D and S are 2x2 matrices.

Thanks.

 [~,idx]=sort(diag(D));

 D=D(idx,idx);

Thank you for your reply.

I tried this but I got the eigenvalues not in the diagonal. Is it right?

Dt1 =

          0    -0.5782
         0.6702   0

D(idx,idx) not D(idx,:)
