   * \par Description
   * Please for details consult the proper documentation of the external
   * library cephes.
   *
   * \par Header file
   *
   * \code
   * #include <nt2/toolbox/cephes/include/functions/dawsn.hpp>
   * \endcode
   *
   *
   * \synopsis
   *
   * \code
   * namespace nt2
   * {
   *   namespace cephes
   *   {
   *     template <class A0>
   *       meta::call<tag::dawsn_(A0)>::type
   *       dawsn(const A0 & a0);
   *   }
   * }
   * \endcode
   *
   * \param a0 the unique parameter of dawsn
   *
   * \return a value of the same type as the parameter
   *
   * \par Notes
   * In SIMD mode, this function acts elementwise on the inputs vectors elements
   * \par
   * When calling external library, nt2 simply encapsulates the
   * original proper call to provide easy use.
   * \par
   * Remenber that SIMD implementation is therefore merely
   * mapping the scalar function to each SIMD vectors elements
   * and will not provide acceleration, but ease.
   * \par
   * cephes library defines functions for float and double entries.
   * \par
   * As they are written in C the original name of the float version is
   * generally terminated by and extra 'f',
   * this is not the case for the nt2 version which dispatch to
   * the correct function according to the inputs types.
