Detailed Description

template<typename Scalar_, int Options_>
class Eigen::Map< Quaternion< Scalar_ >, Options_ >

Expression of a quaternion from a memory buffer.

Template Parameters

Scalar_	the type of the Quaternion coefficients
Options_	see class Map

This is a specialization of class Map for Quaternion. This class allows to view a 4 scalar memory buffer as an Eigen's Quaternion object.
