Detailed Description

template<typename _Scalar, int PacketAccess>
class Map< const Quaternion< _Scalar >, PacketAccess >

Quaternion expression mapping a constant memory buffer.

Parameters:
_Scalar the type of the Quaternion coefficients
PacketAccess 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.

Constructor & Destructor Documentation

template<typename _Scalar , int PacketAccess>
EIGEN_STRONG_INLINE Map< const Quaternion< _Scalar >, PacketAccess >::Map ( const Scalar *  coeffs  )  [inline]

Constructs a Mapped Quaternion object from the pointer coeffs

The pointer coeffs must reference the four coeffecients of Quaternion in the following order: 

 *coeffs == {x, y, z, w}

If the template parameter PacketAccess is set to Aligned, then the pointer coeffs must be aligned.

template<typename _Scalar , int PacketAccess>
const Coefficients& Map< const Quaternion< _Scalar >, PacketAccess >::coeffs (  )  const [inline]
Returns:
a read-only vector expression of the coefficients (x,y,z,w)

Reimplemented from QuaternionBase< Map< const Quaternion< _Scalar >, PacketAccess > >.
