class RRcppeigen(RPackage):
"""R and 'Eigen' integration using 'Rcpp'. 'Eigen' is a C++ template
library for linear algebra: matrices, vectors, numerical solvers and
related algorithms. It supports dense and sparse matrices on integer,
floating point and complex numbers, decompositions of such matrices, and
solutions of linear systems. Its performance on many algorithms is
comparable with some of the best implementations based on 'Lapack' and
level-3 'BLAS'. The 'RcppEigen' package includes the header files from the
'Eigen' C++ template library (currently version 3.2.8). Thus users do not
need to install 'Eigen' itself in order to use 'RcppEigen'. Since version
3.1.1, 'Eigen' is licensed under the Mozilla Public License (version 2);
earlier version were licensed under the GNU LGPL version 3 or later.
'RcppEigen' (the 'Rcpp' bindings/bridge to 'Eigen') is licensed under the
GNU GPL version 2 or later, as is the rest of 'Rcpp'."""
