# The math/lapack port

## lapack-3.1.1p3 – library of Fortran 77 linear algebra subroutines

## Description

    LAPACK is written in Fortran77 and provides routines for solving
    systems of simultaneous linear equations, least-squares solutions of
    linear systems of equations, eigenvalue problems, and singular value
    problems. The associated matrix factorizations (LU, Cholesky, QR,
    SVD, Schur, generalized Schur) are also provided, as are related
    computations such as reordering of the Schur factorizations and
    estimating condition numbers. Dense and banded matrices are handled,
    but not general sparse matrices. In all areas, similar functionality
    is provided for real and complex matrices, in both single and double
    precision.
