- Comprised of four numerical (iterative) methods for computing the singular value decomposition (SVD) of large sparse matrices using double precision Fortran 77.
- 3664
- Systems Optimization Laboratory
- Code for sparse linear equations (symmetric or general) and sparse least squares, and updating a dense square factorization L C = U.
- 3665
- Y12m
- Fortran 77 code that solves sparse systems of linear algebraic equations by Gaussian elimination.

- Fortran 95 Codes for Convex Network Optimization
- Modules for random number generation, plotting, sorting, ranking, combinatorics, network optimization, and optimization. Written in FWEB by Aleksandar Donev.
- 3668
- Linear Programming
- Ratfor code for the primal-dual log barrier form of the interior point LP solver of Lustig, Marsten and Shanno, ORSA J Opt 1992.

- TANGO: Trustable Algorithms for Nonlinear General Optimization
- A set of Fortran routines for optimization developed at the University of São Paulo. Includes downloads, test problems, and related publications.
- 3675
- EISPACK
- A collection of Fortran subroutines that compute the eigenvalues and eigenvectors of nine classes of matrices: complex general, complex Hermitian, real general, real symmetric, real symmetric banded, real symmetric tridiagonal, special real tridiagonal, generalized real, and generalized real symmetric matices. In addition, two routines are included that use singular value decomposition to solve certain least-squares problems.
