Detailed Description

template<typename Derived>
class Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >

Base class providing read-only coefficient access to matrices and arrays.

Template Parameters

Derived	Type of the derived class
ReadOnlyAccessors	Constant indicating read-only access

This class defines the operator() const function and friends, which can be used to read specific entries of a matrix or array.

Member Function Documentation

◆ coeff() [1/2]

template<typename Derived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE CoeffReturnType Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >::coeff ( Index index ) const

inline

Short version: don't use this function, use operator[](Index) const instead.

Long version: this function is similar to operator[](Index) const , but without the assertion. Use this for limiting the performance cost of debugging code when doing repeated coefficient access. Only use this when it is guaranteed that the parameter index is in range.

If EIGEN_INTERNAL_DEBUGGING is defined, an assertion will be made, making this function equivalent to operator[](Index) const .

See also: operator[](Index) const, coeffRef(Index), coeff(Index,Index) const

◆ coeff() [2/2]

template<typename Derived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE CoeffReturnType Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >::coeff	(	Index	row,
		Index	col
	)		const

inline

Short version: don't use this function, use operator()(Index,Index) const instead.

Long version: this function is similar to operator()(Index,Index) const , but without the assertion. Use this for limiting the performance cost of debugging code when doing repeated coefficient access. Only use this when it is guaranteed that the parameters row and col are in range.

If EIGEN_INTERNAL_DEBUGGING is defined, an assertion will be made, making this function equivalent to operator()(Index,Index) const .

◆ operator[]()

template<typename Derived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE CoeffReturnType Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >::operator[] ( Index index ) const

inline

Returns: the coefficient at given index.

This method is allowed only for vector expressions, and for matrix expressions having the LinearAccessBit.

See also: operator[](Index), operator()(Index,Index) const, x() const, y() const, z() const, w() const

◆ rows()

template<typename Derived >

EIGEN_DEVICE_FUNC Index Eigen::EigenBase< Derived >::rows ( ) const

inline

Returns: the number of rows.

◆ size()

template<typename Derived >

EIGEN_DEVICE_FUNC Index Eigen::EigenBase< Derived >::size ( ) const

inline

Returns: the number of coefficients, which is rows()*cols().

See also: rows(), cols(), SizeAtCompileTime.

◆ w()

template<typename Derived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE CoeffReturnType Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >::w ( ) const

inline

equivalent to operator[](3).

◆ x()

template<typename Derived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE CoeffReturnType Eigen::DenseCoeffsBase< Derived, ReadOnlyAccessors >::x ( ) const

inline

equivalent to operator[](0).

◆ y()
