Constructor & Destructor Documentation

◆ ~SparseMapBase()

template<typename Derived >
Eigen::SparseMapBase< Derived, WriteAccessors >::~SparseMapBase ( )
inline

Empty destructor

Member Function Documentation

◆ coeffRef()

template<typename Derived >
Scalar & Eigen::SparseMapBase< Derived, WriteAccessors >::coeffRef ( Index row,
Index col )
inline

Returns
a non-const reference to the value of the matrix at position i, j

If the element does not exist then it is inserted via the insert(Index,Index) function which itself turns the matrix into a non compressed form if that was not the case.

This is a O(log(nnz_j)) operation (binary search) plus the cost of insert(Index,Index) function if the element does not already exist.

◆ innerIndexPtr() [1/2]

template<typename Derived >
StorageIndex * Eigen::SparseMapBase< Derived, WriteAccessors >::innerIndexPtr ( )
inline

Returns
a const pointer to the array of inner indices. This function is aimed at interoperability with other libraries.
See also
valuePtr(), outerIndexPtr()

◆ innerIndexPtr() [2/2]

template<typename Derived >
const StorageIndex * Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::innerIndexPtr ( ) const
inline

Returns
a const pointer to the array of inner indices. This function is aimed at interoperability with other libraries.
See also
valuePtr(), outerIndexPtr()

◆ innerNonZeroPtr() [1/2]

template<typename Derived >
StorageIndex * Eigen::SparseMapBase< Derived, WriteAccessors >::innerNonZeroPtr ( )
inline

Returns
a const pointer to the array of the number of non zeros of the inner vectors. This function is aimed at interoperability with other libraries.
Warning
it returns the null pointer 0 in compressed mode

◆ innerNonZeroPtr() [2/2]

template<typename Derived >
const StorageIndex * Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::innerNonZeroPtr ( ) const
inline

Returns
a const pointer to the array of the number of non zeros of the inner vectors. This function is aimed at interoperability with other libraries.
Warning
it returns the null pointer 0 in compressed mode

◆ outerIndexPtr() [1/2]

template<typename Derived >
StorageIndex * Eigen::SparseMapBase< Derived, WriteAccessors >::outerIndexPtr ( )
inline

Returns
a const pointer to the array of the starting positions of the inner vectors. This function is aimed at interoperability with other libraries.
See also
valuePtr(), innerIndexPtr()

◆ outerIndexPtr() [2/2]

template<typename Derived >
const StorageIndex * Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::outerIndexPtr ( ) const
inline

Returns
a const pointer to the array of the starting positions of the inner vectors. This function is aimed at interoperability with other libraries.
See also
valuePtr(), innerIndexPtr()

◆ valuePtr() [1/2]

template<typename Derived >
Scalar * Eigen::SparseMapBase< Derived, WriteAccessors >::valuePtr ( )
inline

Returns
a const pointer to the array of values. This function is aimed at interoperability with other libraries.
See also
innerIndexPtr(), outerIndexPtr()

◆ valuePtr() [2/2]

template<typename Derived >
const Scalar * Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::valuePtr ( ) const
inline

Returns
a const pointer to the array of values. This function is aimed at interoperability with other libraries.
