In the module SelfAdjointEigensolver, the method <<tridiagonal_qr_step>> together with some code in <<SelfAdjointEigenSolver<..>& SelfAdjointEigenSolver<MatrixType>::compute(..)>> computes the eigenvalues and, optionally, the eigenvectors of a tridiagonal symmetric matrix. This method should be exposed to end-users and provide and interface to self-adjoint tridiagonal matrices and two vectors containing the diagonal and off-diagonal elements respectively.
