Based on the classic truncated Newton algorithm for nonlinear optimization, a new subspace accelerated truncated Newton algorithm is presented for large-scale symmetric sparse extreme eigenvalue problems. The convergence properties are proved and numerical experiments are done. The numerical results match the convergence analysis,which showing the new algorithm is effective.
