Approximate inverse based multigrid solution of large sparse linear systems
(1988)In this thesis we study the approximate inverse based multigrid algorithm FAPIN for the solution of large sparse linear systems of equations. This algorithm, which is closely related to the well known multigrid V-cycle, ... -
Parallel algorithms for the iterative solution of large sparse linear systems
(1982)In this thesis we are concerned with iterative parallel algorithms for solving finite difference equations arising from boundary value problems. We propose various new methods based on approximate inverses. The Jacobi ...
