Cython interface between the numpy arrays and the Matrix/Array classes of the Eigen C++ library
copied from cf-staging / eigencyEigency is a Cython interface between Numpy arrays and Matrix/Array objects from the Eigen C++ library. It is intended to simplify the process of writing C++ extensions using the Eigen library. Eigency is designed to reuse the underlying storage of the arrays when passing data back and forth, and will thus avoid making unnecessary copies whenever possible. Only in cases where copies are explicitly requested by your C++ code will they be made.
