On the x86 architecture, the SSE2 instruction set is not enabled by default. Use \c -msse2 to enable it, and Eigen will then automatically enable its vectorized paths. On x86-64 and AltiVec-based architectures, vectorization is enabled by default. On the x86 architecture, the SSE2 instruction set is not enabled by default.

\warning \redstar In most cases it is enough to include the \c Eigen/Core header only to get started with Eigen. However, some features presented in this tutorial require the Array module to be included (\c \#include \c <Eigen/Array>). Those features are highlighted with a red star \redstar. Notice that if you want to include all dense (i.e. all except sparse) Eigen functionality at once, you can do:
\code
#include <Eigen/Dense>
\endcode
This slows compilation by roughly 10-20% but at least you don't have to worry anymore about including the correct files!
