parts of the C++ Boost libraries are used to provide various functionality, like ordinary differential equations integrators. The source for the 1.54.0 release is shipped with the module’s source code. Some of the libraries used need to be compiled. Boost is released under the terms of the Boost Software License, v1.0 (see also http://www.boost.org/users/license.html)
As of v1.1.11 we have started removing the dependency from Boost. The use of Boost is thus deprecated.
the Eigen template library for linear algebra. Almost every operation involving matrices and vectors is performed through Eigen. Eigen provides convenient type definitions for vectors and matrices (of arbitrary dimensions) and the corresponding operations. Have a look here for a quick reference guide to the API and at the getting started guide to get started. Eigen is distributed under the terms of the Mozilla Public License, v2.0
Third-party code snippets:
- Fortran subroutines dsyevv3, dsyevh3, dsyevj3 for the diagonalization of 3x3 Hermitian matrices. These subroutines were copied verbatim from the source code provided by Joachim Kopp and described in [Kop08] (also available on the arXiv) The diagonalization subroutines are made available under the terms of the GNU Lesser General Public License, v2.1
- C++ cnpy library for saving arrays in C++ into Numpy arrays. The library is from Carl Rogers under the terms of the MIT License. The version in PCMSolver is slightly different.
