%global _description\
LAPACK (Linear Algebra PACKage) is a standard library for numerical\
linear algebra. LAPACK provides routines for solving systems of\
simultaneous linear equations, least-squares solutions of linear\
systems of equations, eigenvalue problems, and singular value\
problems. Associated matrix factorizations (LU, Cholesky, QR, SVD,\
Schur, and generalized Schur) and related computations (i.e.,\
reordering of Schur factorizations and estimating condition numbers)\
are also included. LAPACK can handle dense and banded matrices, but\
not general sparse matrices. Similar functionality is provided for\
real and complex matrices in both single and double precision. LAPACK\
is coded in Fortran90 and built with gcc.\
