  • Published 2013 in ACM Southeast Regional Conference


Consider a solution of systems of linear equations Ax = b when A is a symmetric positive definite matrix. We solve the equations using a direct method using Cholesky factorization, A = LLT or a preconditioned iterative method. In this paper, we are proposing a new preconditioner based on the iterative recursion to improve the performance of conjugate… (More)
