Eigen is a high-level C++ library of template headers for linear algebra, matrix and vector operations, geometrical transformations, numerical solvers and related algorithms. Eigen is open-source software licensed under the Mozilla Public License 2.0 since version 3.1.1. Earlier versions were licensed under the GNU Lesser General Public License.[1]
Eigen is implemented using the expression templates metaprogramming technique, meaning it builds expression trees at compile time and generates custom code to evaluate these. Using expression templates and a cost model of floating point operations, the library performs its own loop unrolling and vectorization.[2] Eigen itself can provide BLAS and a subset of LAPACK interfaces.[3]

The eigen_blas library is complete. The eigen_lapack currently implements cholesky and lu decomposition. Contact us if you want to help.
