%description
LAPACK 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.

%description -n blas-devel
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
and built with gfortran. BLAS manual pages are available in the
blas-man package.

%package -n liblapacke3
Summary:        LAPACKE development files
Group:          Development/Libraries/C and C++

%description -n liblapacke3
This library provides a native C interface to LAPACK routines available
at www.netlib.org/lapack to facilitate usage of LAPACK functionality 
for C programmers.

This implementation introduces:
- row-major and column-major matrix layout controlled by the first function 
  parameter;
- an implementation with working arrays (middle-level interface) as well as 
  without working arrays (high-level interface);
- input scalars passed by value;
- error code as a return value instead of the INFO parameter.
