Detailed Description

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

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

This base class provides the const low-level accessors (e.g. coeff, coeffRef) of dense Map and Block objects with direct access. Typical users do not have to directly deal with this class.

This class can be extended by through the macro plugin EIGEN_MAPBASE_PLUGIN. See customizing Eigen for details.

The Derived class has to provide the following two methods describing the memory layout:

Index innerStride() const;

Index outerStride() 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.

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