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
xtensor-blas is a header-only library. We provide a package for the mamba (or conda) package manager.
mamba install -c conda-forge xtensor-blas
which will also install the core xtensor package.
Or you can directly install it from the sources:
cmake -D CMAKE_INSTALL_PREFIX=your_install_prefix
make install
To build the tests or actually use xtensor-blas, you will need binaries for
openblaslapack
which are also available on conda-forge.
You can play with xtensor interactively in a Jupyter notebook right now! Just click on the binder link below:
The C++ support in Jupyter is powered by the xeus-cling C++ kernel. Together with xeus-cling, xtensor enables a similar workflow to that of NumPy with the IPython Jupyter kernel.
