45 * @brief Header definitions for the standard LAPACK library.
47 * This is the subset of LAPACK routines used for the
48 * linear algebra operations in Gromacs. Most of the execution time
49 * will be spent in the BLAS routines, which you hopefully have an
50 * optimized version of. Gromacs includes reference implementations
51 * of both BLAS and LAPACK so it compiles everywhere, but you should
52 * really try to find a vendor or otherwise optimized version at least
53 * of BLAS for better performance.
55 * Do NOT use this code for other purposes - we only provide this as a
56 * simple fallback/reference implementation when no optimized BLAS
57 * is present. If you need an implementation for your own code
58 * there are several much faster versions out there.
60 * All routines are compatible with the LAPACK/BLAS reference implementations,
61 * meaning they assume fortran-style matrix row/column organization.
63 * There is plenty of documentation for these routines available
64 * at http://www.netlib.org/lapack , so there is no point in repeating
