Detailed Description

template<typename Derived>
class Eigen::MapBase< Derived, WriteAccessors >

Base class for non-const dense Map and Block expression with direct access.

This base class provides the non-const low-level accessors (e.g. coeff and coeffRef) of dense Map and Block objects with direct access. It inherits MapBase<Derived, ReadOnlyAccessors> which defines the const variant for reading specific entries.

Member Function Documentation

◆ coeff() [1/2]

template<typename Derived >
const Scalar & Eigen::MapBase< Derived, ReadOnlyAccessors >::coeff ( Index index) const
inline

This is an overloaded version of DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index) const provided to by-pass the creation of an evaluator of the expression, thus saving compilation efforts.

See DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index) const for details.

◆ coeff() [2/2]

template<typename Derived >
const Scalar & Eigen::MapBase< Derived, ReadOnlyAccessors >::coeff ( Index rowId,
Index colId ) const
inline

This is an overloaded version of DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index,Index) const provided to by-pass the creation of an evaluator of the expression, thus saving compilation efforts.

See DenseCoeffsBase<Derived,ReadOnlyAccessors>::coeff(Index) const for details.

◆ coeffRef() [1/2]

template<typename Derived >
const Scalar & Eigen::MapBase< Derived, ReadOnlyAccessors >::coeffRef ( Index index) const
inline

This is the const version of coeffRef(Index) which is thus synonym of coeff(Index). It is provided for convenience.

◆ coeffRef() [2/2]

template<typename Derived >
const Scalar & Eigen::MapBase< Derived, ReadOnlyAccessors >::coeffRef ( Index rowId,
Index colId ) const
inline

This is the const version of coeffRef(Index,Index) which is thus synonym of coeff(Index,Index). It is provided for convenience.

◆ cols()

template<typename Derived >
EIGEN_CONSTEXPR Index Eigen::MapBase< Derived, ReadOnlyAccessors >::cols ( ) const
inline

Returns
the number of columns.
See also
rows(), ColsAtCompileTime

◆ rows()

template<typename Derived >
EIGEN_CONSTEXPR Index Eigen::MapBase< Derived, ReadOnlyAccessors >::rows ( ) const
inline

Returns
the number of rows.
