Detailed Description

template<typename Derived>
class Eigen::EigenBase< Derived >

Common base class for all classes T such that MatrixBase has an operator=(T) and a constructor MatrixBase(T).

In other words, an EigenBase object is an object that can be copied into a MatrixBase.

Besides MatrixBase-derived classes, this also includes special matrix classes such as diagonal matrices, etc.

Notice that this class is trivial, it is only used to disambiguate overloaded functions.

Member Typedef Documentation

◆ Index

template<typename Derived >
typedef Eigen::Index Eigen::EigenBase< Derived >::Index

The interface type of indices.

To change this, #define the preprocessor symbol EIGEN_DEFAULT_DENSE_INDEX_TYPE.

See also
StorageIndex, Preprocessor directives. DEPRECATED: Since Eigen 3.3, its usage is deprecated. Use Eigen::Index instead. Deprecation is not marked with a doxygen comment because there are too many existing usages to add the deprecation attribute.

Member Function Documentation

◆ cols()

template<typename Derived >
EIGEN_CONSTEXPR Index Eigen::EigenBase< Derived >::cols ( ) const
inline
Returns
the number of columns.
See also
rows(), ColsAtCompileTime

◆ derived() [1/2]

template<typename Derived >
Derived & Eigen::EigenBase< Derived >::derived ( )
inline
Returns
a reference to the derived object

◆ derived() [2/2]

template<typename Derived >
const Derived & Eigen::EigenBase< Derived >::derived ( ) const
inline
Returns
a const reference to the derived object

◆ rows()

template<typename Derived >
EIGEN_CONSTEXPR Index Eigen::EigenBase< Derived >::rows ( ) const
inline
Returns
the number of rows.
See also
cols(), RowsAtCompileTime

◆ size()

template<typename Derived >
EIGEN_CONSTEXPR Index Eigen::EigenBase< Derived >::size ( ) const
inline
Returns
the number of coefficients, which is rows()*cols().
