Includes a block-band matrix solver and a Fortran 90 makefile with corresponding dependency generator. By Udo Grabowski.

Fortran 90 modules by Ernst Meese for the compressed sparse row (CSR) and the modified sparse row (MSR) data storage formats, a very general incomplete LU factorisation routine, the Krylov subspace solvers CGS, BiCGSTAB and GMRES.

Collection of Fortran 77 subroutines for solving large sparse linear systems by adaptive accelerated iterative algorithms.

Fortran 77 subroutines for solving large sparse linear systems by adaptive accelerated iterative algorithms.

Software by Rasmus Munk Larsen for large and sparse SVD calculations, with versions in Fortran and Matlab.

The optimqr program will read a description of the sparsity pattern of some system matrix for system of linear equations. It will then apply heuristic branch and bound search to find a near-optimal ordering of the rows and columns of the system matrix...

Code by Yousef Saad and Jun Zhang to solve general sparse linear systems by using Krylov subspace methods preconditioned by some multi-level block ILU (BILUM) preconditioning techniques.

Fortran 77 code for sparse matrix multiplication, transposition, and format conversion.

Comprised of four numerical (iterative) methods for computing the singular value decomposition (SVD) of large sparse matrices using double precision Fortran 77.

Fortran 77 code that solves sparse systems of linear algebraic equations by Gaussian elimination.
