Boost Linear and Multilinear Algebra Library

Language License Documentation Wiki Mailing List Gitter

Boost.uBLAS is part of the Boost C++ Libraries. It is directed towards scientific computing on the level of basic linear and multilinear algebra operations with tensors, matrices and vectors.

Documentation

uBLAS is documented at boost.org. The tensor extension has also a wiki page.

License

Distributed under the Boost Software License, Version 1.0.

Properties

  • Header-only
  • Tensor extension requires C++17 compatible compiler
  • Unit-tests require Boost.Test
