Detailed Description

Namespace for preconditioners of linear system solvers.

This namespace contains the following preconditioners for iterative solvers linear systems.

1. Diagonal - is diagonal or Jacobi preconditioner - seeNetlib
2. ILU0 - is Incomplete LU preconditioner with the same sparsity pattern as the original matrix - see Wikipedia
3. ILUT - is Incomplete LU preconiditoner with thresholding - see paper by Y. Saad
