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

col()

template<typename XprType >

EIGEN_STRONG_INLINE Index Eigen::InnerIterator< XprType >::col ( ) const

inline

Returns

the column index of the current coefficient.

Definition at line 56 of file CoreIterators.h.

index()

template<typename XprType >

EIGEN_STRONG_INLINE Index Eigen::InnerIterator< XprType >::index ( ) const

inline

Returns

the column or row index of the current coefficient.

Definition at line 52 of file CoreIterators.h.

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.

Definition at line 58 of file CoreIterators.h.

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

Definition at line 50 of file CoreIterators.h.

row()

template<typename XprType >

EIGEN_STRONG_INLINE Index Eigen::InnerIterator< XprType >::row ( ) const

inline

Returns

the row index of the current coefficient.

Definition at line 54 of file CoreIterators.h.

value()

template<typename XprType >

EIGEN_STRONG_INLINE Scalar Eigen::InnerIterator< XprType >::value ( ) const

inline

Returns

the value of the current coefficient.
