Biconjugate direction methods in Krylov subspaces
Валерий Павлович Ильин · Journal of Applied and Industrial Mathematics · 2010
The paper addresses the orthogonal and variational properties of a family of iterative algorithms in Krylov subspaces for solving the systems of linear algebraic equations (SLAE) with sparse nonsymmetric matrices. There are proposed and studied a biconjugate residual method, squared biconjugate residual method, and stabilized conjugate residual method. Some results of numerical experiments are given for a series of model problems as well.
