Detailed Description

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

Quaternion expression mapping a constant 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.

Constructor & Destructor Documentation

◆ Map() [1/4]

template<typename Scalar_, int Options_>

Eigen::Map< const Quaternion< Scalar_ >, Options_ >::Map ( const 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}

Eigen::QuaternionBase< Map< const Quaternion< Scalar_ >, Options_ > >::x

EIGEN_CONSTEXPR CoeffReturnType x() const

Definition Quaternion.h:60

Eigen::QuaternionBase< Map< const Quaternion< Scalar_ >, Options_ > >::w

EIGEN_CONSTEXPR CoeffReturnType w() const

Definition Quaternion.h:66

Eigen::QuaternionBase< Map< const Quaternion< Scalar_ >, Options_ > >::y

EIGEN_CONSTEXPR CoeffReturnType y() const

Definition Quaternion.h:62

Eigen::QuaternionBase< Map< const Quaternion< Scalar_ >, Options_ > >::z

EIGEN_CONSTEXPR CoeffReturnType z() const

Definition Quaternion.h:64

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

◆ Map() [2/4]

Eigen::Map< const Quaternion< Scalar_ >, MapOptions, Stride<0, 0> >::Map	(	PointerArgType	dataPtr,
		const Stride<0, 0> &	stride = StrideType() )

inlineexplicit

Constructor in the fixed-size case.

Parameters

dataPtr	pointer to the array to map
stride	optional Stride object, passing the strides.

◆ Map() [3/4]

Eigen::Map< const Quaternion< Scalar_ >, MapOptions, Stride<0, 0> >::Map	(	PointerArgType	dataPtr,
		Index	size,
		const Stride<0, 0> &	stride = StrideType() )

inline

Constructor in the dynamic-size vector case.

Parameters

dataPtr	pointer to the array to map
size	the size of the vector expression
stride	optional Stride object, passing the strides.

◆ Map() [4/4]

Eigen::Map< const Quaternion< Scalar_ >, MapOptions, Stride<0, 0> >::Map	(	PointerArgType	dataPtr,
		Index	rows,
		Index	cols,
		const Stride<0, 0> &	stride = StrideType() )

inline

Constructor in the dynamic-size matrix case.

Parameters

dataPtr	pointer to the array to map
rows	the number of rows of the matrix expression
cols	the number of columns of the matrix expression
stride	optional Stride object, passing the strides.
