PCGPAK2(R) is a library of Fortran 77 subroutines for the solution of large, sparse linear systems. It uses advanced iterative algorithms to minimize the time and storage required to solve the problems. PCGPAK2(R) employs several conjugate-gradient-type solvers. The library contains several matrix preconditioning routines to speed convergence. The user has full control in combining the solver and preconditioner for the most efficient problem solution. PCGPAK2(R) uses sparse data structures for efficient storage of linear systems.
