License BSD-new  LAPACK (Linear Algebra Package) is a standard
software library for numerical linear algebra. It provides
routines for solving systems of linear equations and linear
least squares, eigenvalue problems, and singular value
decomposition. It also includes routines to implement the
associated matrix factorizations such as LU, QR, Cholesky and
Schur decomposition. LAPACK was originally written in FORTRAN
77, but moved to Fortran 90 in version 3.2 (2008).[1] The
routines handle both real and complex matrices in both single
and double precision.  LAPACK can be seen as the successor to
the linear equations and linear least-squares routines of
LINPACK and the eigenvalue routines of EISPACK. LINPACK was
designed to run on the then-modern vector computers with
