+**EigenPy** is an open source framework which allows to bind the famous [Eigen](http://eigen.tuxfamily.org) C++ library in Python via Boost.Python.
 
 **EigenPy** provides:
  - full memory sharing between Numpy and Eigen avoiding memory allocation
  - full support Eigen::Ref avoiding memory allocation
+ - full support of the Eigen::Tensor module
  - exposition of the Geometry module of Eigen for easy code prototyping
  - standard matrix decomposion routines of Eigen such as the Cholesky decomposition, SVD decomposition, QR decomposition, and etc.
  - full support of SWIG objects
+ - full support of runtime declaration of Numpy scalar types
+ - extended API to expose std::vector types
