A collection of Fortran solvers for the initial value problem for ordinary differential equation systems.

Codes for ordinary differential equations from Netlib.

Multiple precision arithmetic.

Fortran 77 code for solving nonlinear equations and nonlinear least squares problems. Five algorithmic paths each include a core subroutine and an easy-to-use driver. The algorithms proceed either from an analytic specification of the Jacobian matrix ...

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...

Fortran IV subroutines for computing a few eigenvalues of a large (sparse) symmetric matrix.

Fortran 77 routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.

Solves the large, sparse, symmetric generalized eigenproblem.

Codes to compute eigenvalues and eigenvectors using the Lanczos algorithm.

A packages for solving large sparse linear systems by iterative methods.
