The eigenvalues remain unchanged under similarity transformation

$\displaystyle A \to B = Q^{-1}AQ\, .$

The eigenvectors are transformed according to the change of basis described by

. That is, An eigenvector

associated with eigenvalue $\lambda$ corresponds to eigenvector $v = Q^{-1}w$ of

associated with the same eigenvalue.
