%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 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.
