Boost.uBLAS: C++ linear and multilinear algebra library

Boost.uBLAS Linear Algebra Library

Boost.uBLAS is part of the Boost C++ Libraries. It is directed towards scientific computing on the level of basic linear algebra constructions with matrices and vectors and their corresponding abstract operations.

Simple Example

#include <boost/numeric/ublas/tensor.hpp> 
#include <iostream>

int main()
{
  using namespace boost::numeric::ublas::index;
  using tensor  = boost::numeric::ublas::tensor_dynamic<float>;
  auto ones     = boost::numeric::ublas::ones<float>{};

  tensor A = ones(3,4,5);
  tensor B = ones(4,6,3,2);

  tensor C = 2*ones(5,6,2) + A(_i,_j,_k)*B(_j,_l,_i,_m) + 5;
  
  // Matlab Compatible Formatted Output
  std::cout << "C=" << C << ";" << std::endl;
}

Requirements

• Boost.uBlas requires a C++20 compatible compiler
  • gcc version >= 10.x.x
  • clang version >= 10.x.x
  • msvc version >= 14.28
• Unit-tests require Boost.Test

Discussions and Questions

• Be sure to have read our code of conduct and Boost's discussion policy
• Contributors and maintainers mainly use Discussions (previously Gitter) to discuss library design or governance topics.
• Users of the library can choose between the following platforms preferably Gitter, the Boost developers mailing list using the [ublas] tag at the beginning of the subject line or Stackoverflow using boost-ublas or ublas tags
• Contact the maintainers Cem, David or Stefan if you have suggestions

Contribution

• Be sure that you have read our contribution guidelines and our code of conduct
• If you want to report a bug, create an issue
• If you want to submit a patch, create pull request against develop branch.
