/*!\brief Compilation switch for (de-)activation of the Blaze vectorization.
// \ingroup config
//
// This compilation switch enables/disables vectorization of mathematical expressions via
// the SSE, AVX, and/or MIC instruction sets. In case the switch is set to 1 (i.e. in case
// vectorization is enabled), the Blaze library attempts to vectorize the linear algebra
// operations by SSE, AVX, and/or MIC intrinsics (depending on which instruction set is
// available on the target platform). In case the switch is set to 0 (i.e. vectorization
// is disabled), the Blaze library chooses default, non-vectorized functionality for the
// operations. Note that deactivating the vectorization may pose a severe performance
// limitation for a large number of operations!
//
// Possible settings for the vectorization switch:
//  - Deactivated: \b 0
//  - Activated  : \b 1 (default)
//
// \note It is possible to (de-)activate vectorization via command line or by defining this
// symbol manually before including any Blaze header file:

   \code
   g++ ... -DBLAZE_USE_VECTORIZATION=1 ...
   \endcode

   \code
   #define BLAZE_USE_VECTORIZATION 1
   #include <blaze/Blaze.h>
   \endcode

/*!\brief Compilation switch for enabling/disabling vectorization by means of the Sleef library.
// \ingroup config
//
// For several complex operations Blaze can make use of the Sleef library for vectorization
// (https://github.com/shibatch/sleef). This compilation switch enables/disables the vectorization
// by means of Sleef. In case the switch is set to 1, Blaze uses Sleef for instance for the
// vectorized computation of trigonometric functions (i.e. \c sin(), \c cos(), \c tan(), etc.)
// and exponential functions (i.e. \c exp(), \c log(), ...).
