   Eigen is a lightweight C++ template library for vector and matrix math,
   a.k.a. linear algebra. Unlike most other linear algebra libraries, Eigen
   focuses on the simple mathematical needs of applications: games and other
   OpenGL apps, spreadsheets and other office apps, etc. Eigen is dedicated to
   providing optimal speed with GCC.
