Eigen::Map< Quaternion< _Scalar >, _Options > Class Template Reference

Detailed Description

template<typename _Scalar, int _Options>
class Eigen::Map< Quaternion< _Scalar >, _Options >

Expression of a quaternion from a memory buffer.

Template Parameters
_Scalarthe type of the Quaternion coefficients
_Optionssee 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

◆ Map()

template<typename _Scalar, int _Options>
Eigen::Map< Quaternion< _Scalar >, _Options >::Map ( Scalar * coeffs)
inlineexplicit

Constructs a Mapped Quaternion object from the pointer coeffs

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

*coeffs == {x, y, z, w}
CoeffReturnType z() const
Definition Quaternion.h:70
CoeffReturnType y() const
Definition Quaternion.h:68
CoeffReturnType w() const
Definition Quaternion.h:72
CoeffReturnType x() const
Definition Quaternion.h:66

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