The method of diagonalizing Hermitian matrices based on a polynomial expansion of the Dirac delta function S( E -H) is further refined so as to accelerate the convergence. Improved choices of the bases used for subspace diagonalization of the matrix, along with accuracy controls and estimates, are i
New methods for the iterative calculation of a few of the lowest eigenvalues and corresponding eigenvectors of a generalized eigenvalue problem are proposed. These methods use only multiplication of the A and B matrices on a vector. 0 1994 by John Wiley & Sons, Inc.
