A constraint preconditioner for solving symmetric positive definite systems and application to the helmholtz equations and poisson equations
In this paper, first, by using the diagonally compensated reduction and incomplete Cholesky factorization methods, we construct a constraint preconditioner for solving symmetric positive definite linear systems and then we apply the preconditioner to solve the Helmholtz equations and Poisson equati...
