LASPack LASPack is a package for solving large sparse systems of linear equations like those which arise from the discretization of partial differential equations. The primary aim of LASPack is the implementation of efficient iterative methods for the solution of systems of linear equations. All routines and data structures are optimized for effective usage of resources especially with regard to large sparse matrices. The package can be accessed from an application through a straightforward interface defined in the form of procedure calls. LASPack contains selected state-of-the-art algorithms which are commonly used for large sparse systems like CGN, GMRES, BiCG, QMR, CGS, BiCGStab, and multilevel methods such as the multigrid and conjugate gradient methods preconditioned by multigrid and BPX preconditioners. The implementation is based on an object-oriented approach (although it is programmed in C). Vectors and matrices are defined as new data types in connection with the corresponding supporting routines. The basic operations are implemented in such a way that they allow the programming of linear algebra algorithms in a natural way.
