Detailed Description

template<typename XprType>
class Eigen::InnerIterator< XprType >

An InnerIterator allows to loop over the element of any matrix expression.

Warning
To be used with care because an evaluator is constructed every time an InnerIterator iterator is constructed.

TODO: add a usage example

Member Function Documentation

§ col()

template<typename XprType >
EIGEN_STRONG_INLINE Index Eigen::InnerIterator< XprType >::col ( ) const
inline
Returns
the column index of the current coefficient.

§ index()

template<typename XprType >
EIGEN_STRONG_INLINE Index Eigen::InnerIterator< XprType >::index ( ) const
inline
Returns
the column or row index of the current coefficient.

§ operator bool()

template<typename XprType >
EIGEN_STRONG_INLINE Eigen::InnerIterator< XprType >::operator bool ( ) const
inline
Returns
true if the iterator *this still references a valid coefficient.

§ operator++()

template<typename XprType >
EIGEN_STRONG_INLINE InnerIterator& Eigen::InnerIterator< XprType >::operator++ ( )
inline

Increment the iterator *this to the next non-zero coefficient.

Explicit zeros are not skipped over. To skip explicit zeros, see class SparseView

§ row()

template<typename XprType >
EIGEN_STRONG_INLINE Index Eigen::InnerIterator< XprType >::row ( ) const
inline
Returns
the row index of the current coefficient.

§ value()

template<typename XprType >
EIGEN_STRONG_INLINE Scalar Eigen::InnerIterator< XprType >::value ( ) const
inline
Returns
the value of the current coefficient.
