Detailed Description

template<typename Scalar_, int Options_, typename StorageIndex_>
class Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >

a sparse vector class

Template Parameters

Scalar_ the scalar type, i.e. the type of the coefficients

See http://www.netlib.org/linalg/html_templates/node91.html for details on the storage scheme.

This class can be extended with the help of the plugin mechanism described on the page Extending MatrixBase (and other classes) by defining the preprocessor symbol EIGEN_SPARSEVECTOR_PLUGIN.

Member Function Documentation

◆ coeffRef()

template<typename Scalar_, int Options_, typename StorageIndex_>

Scalar & Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::coeffRef ( Index i )

inline

Returns: a reference to the coefficient value at given index i This operation involves a log(rho*size) binary search. If the coefficient does not exist yet, then a sorted insertion into a sequential buffer is performed.

This insertion might be very costly if the number of nonzeros above i is large.

◆ conservativeResize()

template<typename Scalar_, int Options_, typename StorageIndex_>

void Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::conservativeResize ( Index newSize )

inline

Resizes the sparse vector to newSize, while leaving old values untouched.

If the size of the vector is decreased, then the storage of the out-of bounds coefficients is kept and reserved. Call .data().squeeze() to free extra memory.

See also: reserve(), setZero()

◆ nonZeros()

template<typename Scalar_, int Options_, typename StorageIndex_>

Index Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::nonZeros ( ) const

inline

Returns: the number of non zero coefficients

◆ prune() [1/2]

template<typename Scalar_, int Options_, typename StorageIndex_>

Index Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::prune	(	const Scalar &	reference,
		const RealScalar &	epsilon = NumTraits<RealScalar>::dummy_precision() )

inline

Suppresses all nonzeros which are much smaller than reference under the tolerance epsilon

◆ prune() [2/2]

template<typename Scalar_, int Options_, typename StorageIndex_>

template<class F>

Index Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::prune ( F && keep_predicate )

inline

Prunes the entries of the vector based on a predicate

Template Parameters

F	Type of the predicate.

Parameters

keep_predicate The predicate that is used to test whether a value should be kept. A callable that gets passed in a Scalar value and returns a boolean. If the predicate returns true, the value is kept.

Returns: The new number of structural non-zeros.

◆ resize() [1/4]

template<typename Scalar_, int Options_, typename StorageIndex_>

void Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::resize ( Index newSize )

inline

Resizes the sparse vector to newSize This method deletes all entries, thus leaving an empty sparse vector

See also: conservativeResize(), setZero()

◆ resize() [2/4]

template<typename Scalar_, int Options_, typename StorageIndex_>

void Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::resize	(	Index	rows,
		Index	cols )

inline

Resizes the sparse vector to rows x cols

This method is provided for compatibility with matrices. For a column vector, cols must be equal to 1. For a row vector, rows must be equal to 1.

See also: resize(Index)

◆ resize() [3/4]

template<typename Scalar_, int Options_, typename StorageIndex_>

void Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::resize	(	Index	rows,
		NoChange_t	)

inline

See also: resize(Index,Index)

◆ resize() [4/4]

template<typename Scalar_, int Options_, typename StorageIndex_>

void Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::resize	(	NoChange_t	,
		Index	cols )

inline

See also: resize(Index,Index)

◆ sum()

template<typename Scalar_, int Options_, typename Index_>

internal::traits< SparseVector< Scalar_, Options_, Index_ > >::Scalar Eigen::SparseVector< Scalar_, Options_, Index_ >::sum ( ) const

Overloaded for performance

◆ swap()

template<typename Scalar_, int Options_, typename StorageIndex_>

void Eigen::SparseVector< Scalar_, Options_, StorageIndex_ >::swap ( SparseVector< Scalar_, Options_, StorageIndex_ > & other )

inline

Swaps the values of *this and other. Overloaded for performance: this version performs a shallow swap by swapping pointers and attributes only.
