numcxx - a collection of python compatible classes for linear algebra in C++

Authors: - Jürgen Fuhrmann (http://www.wias-berlin.de/~fuhrmann) - Timo Streckenbach (http://www.wias-berlin.de/~strecken)

Rationale

• Provide lightweight multidimensional linear algebra classes for C++11

• Keep the code reasonably simple and transparent for beginners in order to be useful for teaching

• Study expressive capabilities of modern C++ in the context of numerical algorithms

• Zero copy, reference counted exchange of array data with other packages without copying data, in particular

  • LAPACK (to be installed via system installer)
  • UMFPACK (to be installed via system installer)
  • triangle (provided with numcxx)
  • iterative method templates (provided with numcxx)

• interface to python/numpy (work in progress)

Many ideas used behind this library have been developed in the framework of the WIAS pdelib project, and they evolved over many years. C++11 allows for a standard-conforming and concise implementation, and so this code is as well a concept study.

Anyone expecting a more sophisticated package may have a look at these projects:

• Eigen
• Armadillo
• Blaze
• Trilinos/DOMI
