%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 Fortran77.

LAPACK (Linear Algebra PACKage) jest standardową biblioteką numeryczną
do algebry liniowej. Dostarcza funkcje rozwiązywania: układów równań
liniowych, układów równań metodą najmniejszych kwadratów, problemów
własnych. Zawiera algorytmy faktoryzacji macierzy (LU, Cholesky'ego,
QR, SVD, Schura, uogólnioną Schura) i związanych z tym obliczeń (np.
przenumerowywanie w faktoryzacji Schura i estymację uwarunkowania).
LAPACK może obsługiwać macierze blokowe i pasmowe, ale nie rzadkie w
ogólnym przypadku. Zapewnia funkcjonalność dla macierzy rzeczywistych
i zespolonych, dla liczb pojedynczej i podwójnej precyzji. LAPACK jest
napisany w Fortranie 77.

BLAS (Basic Linear Algebra Subprograms) is a standard library for
numerical algebra. BLAS provides a number of basic algorithms for
linear algebra. BLAS is fast and well-tested, was written in FORTRAN
77.

Warning: this is a reference implementation from Netlib. If possible,
use version optimized for your architecture instead.

%description -n blas -l pl.UTF-8
BLAS (Basic Linear Algebra Subprograms) jest standardową biblioteką
numeryczną algebry. Dostarcza wiele podstawowych algorytmów dla
algebry liniowej. Jest szybka i dobrze przetestowana, została napisana
w Fortranie 77.

Ostrzeżenie: to jest implementacja przykładowa z repozytorium Netlib.
Jeżeli to możliwe, należy używać zamiast niej wersji zoptymalizowanej
pod daną architekturę.
