## Introduction
`xtensor-blas` is an extension to the xtensor library, offering bindings to BLAS and LAPACK libraries through cxxblas and cxxlapack from the [FLENS](https://github.com/michael-lehn/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
## Installation
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
- `openblas`
- `lapack`
which are also available on conda-forge.
## Trying it online
You can play with `xtensor` interactively in a Jupyter notebook right now! Just click on the binder link below:
[](https://mybinder.org/v2/gh/xtensor-stack/xtensor/stable?filepath=notebooks%2Fxtensor.ipynb)
The C++ support in Jupyter is powered by the [xeus-cling](https://github.com/xtensor-stack/xeus-cling) C++ kernel. Together with xeus-cling, xtensor enables a similar workflow to that of NumPy with the IPython Jupyter kernel.
