class RRcppblaze(RPackage):
"""'Blaze' is an open-source, high-performance C++ math library for dense
and sparse arithmetic.
With its state-of-the-art Smart Expression Template implementation
'Blaze' combines the elegance and ease of use of a domain-specific
language with 'HPC'-grade performance, making it one of the most
intuitive and fastest C++ math libraries available. The 'Blaze'
library offers: - high performance through the integration of
'BLAS' libraries and manually tuned 'HPC' math kernels - vectorization
by 'SSE', 'SSE2', 'SSE3', 'SSSE3', 'SSE4', 'AVX', 'AVX2', 'AVX-512',
'FMA', and 'SVML' - parallel execution by 'OpenMP', C++11 threads and
'Boost' threads ('Boost' threads are disabled in 'RcppBlaze') - the
intuitive and easy to use API of a domain specific language - unified
arithmetic with dense and sparse vectors and matrices - thoroughly
tested matrix and vector arithmetic - completely portable, high quality
C++ source code. The 'RcppBlaze' package includes the header files from
the 'Blaze' library with disabling some functionalities related to link
to the thread and system libraries which make 'RcppBlaze' be a
header-only library. Therefore, users do not need to install 'Blaze'
and the dependency 'Boost'. 'Blaze' is licensed under the New (Revised)
BSD license, while 'RcppBlaze' (the 'Rcpp' bindings/bridge to 'Blaze')
is licensed under the GNU GPL version 2 or later, as is the rest of
'Rcpp'. Note that since 'Blaze' has committed to 'C++14' commit to
'C++14' which does not used by most R users from version 3.0, we will
use the version 2.6 of 'Blaze' which is 'C++98' compatible to support
the most compilers and system."""
