Package Information

Description:

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.
