A simple test is given for determining whether a given matrix is the eigenvector matrix of an unknown unreduced symmetric tridiagonal matrix. A list of known necessary conditons is also provided. A lower bound on the separation between eigenvalues of tridiagonals follows from our Theorem 3. Author.
