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.
|
|
Its fixed-size classes are specially optimized for small sizes up to 4,
|
|
although it is theoretically possible to specialize them to any size. They
|
|
never cause dynamic memory applications and the simple operations on them are
|
|
as fast as is possible at least for sizes up to 4 (see below).
|
|
Its dynamic-size classes are more flexible and suitable for larger sizes.
|
|
Both fixed-size and dynamic-size classes use the same underlying C++ code,
|
|
thanks to a curiously recurring template pattern.
