xtensor bindings for BLAS and LAPACK
Introduction
------------
``xtensor-blas`` is an extension to the xtensor library, offering bindings to BLAS and LAPACK libraries through cxxblas and cxxlapack from the FLENS_ project.
``xtensor-blas`` currently provides non-broadcasting ``dot``, ``norm`` (1- and 2-norm for vectors), ``inverse``, ``solve``, ``eig``, ``cross``, ``det``, ``slogdet``, ``matrix_rank``, ``inv``, ``cholesky``, ``qr``, ``svd`` in the ``xt::linalg`` namespace (check the corresponding ``xlinalg.hpp`` header for the function signatures). The functions, and signatures, are trying to be 1-to-1 equivalent to NumPy. Low-level functions to interface with BLAS or LAPACK with xtensor containers are also offered in the blas and lapack namespace.
``xtensor`` and ``xtensor-blas`` require a modern C++ compiler supporting C++14. The following C++ compilers are supported:
- On Windows platforms, Visual C++ 2015 Update 2, or more recent
- On Unix platforms, gcc 4.9 or a recent version of Clang
