Fortran 77 subroutines by Henk A. van der Vorst for the iterative methods GMRESR and BiCGstab(ell). These are methods for the iterative solution of large and typically sparse systems of linear equations with a nonsymmetric matrix.

Fortran 95 interface to the BLAS (Basic Linear Algebra Subprograms). The interface is a subset of the BLAS technical forum standard, covering the functionality of level 2 and 3 legacy BLAS routines (available on most machines).

High performance, scalable, parallel, MPI-based library, intended for solving linear systems of equations involving sparse symmetric positive definite matrices. The library provides various interfaces to solve the system using four phases of direct me...

Codes to solve linear systems with the GMRES and conjugate gradient methods, among other topics.

BLZPACK uses the block Lanczos algorithm to solve (generalized) eigenvalue problems, HLZPACK uses the Lanczos algorithm to solve Hermitian eigenvalue problems, and SKYPACK implements algorithms for matrices having a skyline structure. By Osni Marques.

Binaries compiled with Intel Fortran 9.0, links to LAPACK source code, and make file to create binaries. By David Svoboda.

Toolkit containing various Fortran routines developed over a number of years in support of several code efforts at Los Alamos National Lab. It contains some BLAS-like routines, some LAPACK-like routines, various iterative solvers, and utility routines...

Computes the periodic real Schur decomposition of a matrix product. By Kurt Lust.

Updates a dense square factorization L*C = U, when rows and columns of C are added, deleted or replaced.

A collection of Fortran subroutines that analyze and solve linear equations and linear least-squares problems. The package solves linear systems whose matrices are general, banded, symmetric indefinite, symmetric positive definite, triangular, and tri...
