    • Ritz values and Arnoldi convergence for non-Hermitian matrices 

      Carden, Russell (2012)
      This thesis develops ways of localizing the Ritz values of non-Hermitian matrices. The restarted Arnoldi method with exact shifts, useful for determining a few desired eigenvalues of a matrix, employs Ritz values to refine ...
