44 /* Suppress Cygwin compiler warnings from using newlib version of
53 * @brief Header definitions for the standard BLAS library.
55 * This is the subset of BLAS routines used for the
56 * linear algebra operations in Gromacs.
57 * Do NOT use this for other purposes - we only provide this as a
58 * simple fallback/reference implementation when no optimized BLAS
59 * is present. If you need an implementation for your own code
60 * there are several much faster versions out there.
62 * All routines are compatible with the BLAS reference implementation,
63 * meaning they assume fortran-style matrix row/column organization.
65 * There is plenty of documentation for these routines available
66 * at http://www.netlib.org/blas , so there is no point in repeating
