In Fortran 90, by the MaSe (Matrices Having Structure) Team of the University of Leuven.
Alternative source of LAPACK.
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.
Fortran 95 wrapper that implements matrix operations and computes matrix decompositions using Lapack and the Blas.
Software package for computing small dense and large sparse matrix exponentials in Fortran and Matlab. Usable in C/C++.
Updates a dense square factorization L*C = U, when rows and columns of C are added, deleted or replaced.
Codes to solve linear systems with the GMRES and conjugate gradient methods, among other topics.
Library by Isak Jonsson and Bo Kågström for solving triangular Sylvester-type matrix equations.
Fortran 77 routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.
Implements a Lanczos iteration for symmetric generalized eigenvalue problems. The current version uses the Omega-recurrence to detect loss of orthogonality among the Lanczos vectors.
