This may be a dumb question, forgive me, it's been too long.

I have a real, square matrix Q and I need to factorize it as

        Q = inv(X)*D*X

where D is diagonal.  I think that this means that D contains the
eigenvalues and X contains the eigenvectors of Q.  Is that right?  How do
I get D and X from octave.  The function svd gives the "right and left"
eigenvectors for any matrix.  I thought that for square matrices this
would mean that it would return X but I was wrong.
