libitsol-dev - 1.0.0-3+b1 main

ITSOL is a library of iterative solvers for general sparse linear systems of
equations. ITSOL can be viewed as an extension of the itsol module in SPARSKIT.
It is written in C and offers a selection of recently developed
preconditioners. The preconditioner suite includes:
.
* ILUK (ILU preconditioner with level of fill)
* ILUT (ILU preconditioner with threshold)
* ILUC (Crout version of ILUT)
* VBILUK (variable block preconditioner with level of fill - with automatic
block detection)
* VBILUT (variable block preconditioner with threshold - with automatic
block detection)
* ARMS (Algebraic Recursive Multilevel Solvers -- includes actually several
methods - In particular the standard ARMS and the ddPQ version which uses
nonsymmetric permutations)
.
Note that ITSOL is a scalar package. You may find parallel implementations of
some of the preconditioners listed above in pARMS.
.
This package provides the itsol header files required to compile C/C++ programs
that use ITSOL.
