Detailed Description

template<typename MatrixType, unsigned int _Mode>
class Eigen::SparseSelfAdjointView< MatrixType, _Mode >

Pseudo expression to manipulate a triangular sparse matrix as a selfadjoint matrix.

Parameters

MatrixType	the type of the dense matrix storing the coefficients
Mode	can be either `Lower` or `Upper`

This class is an expression of a sefladjoint matrix from a triangular part of a matrix with given dense storage of the coefficients. It is the return type of MatrixBase::selfadjointView() and most of the time this is the only way that it is used.

Member Function Documentation

◆ operator*()

template<typename MatrixType , unsigned int _Mode>

template<typename OtherDerived >

Product< SparseSelfAdjointView, OtherDerived > Eigen::SparseSelfAdjointView< MatrixType, _Mode >::operator* ( const SparseMatrixBase< OtherDerived > & rhs ) const

inline

Returns: an expression of the matrix product between a sparse self-adjoint matrix *this and a sparse matrix rhs.

Note that there is no algorithmic advantage of performing such a product compared to a general sparse-sparse matrix product. Indeed, the SparseSelfadjointView operand is first copied into a temporary SparseMatrix before computing the product.

◆ rankUpdate()

template<typename MatrixType , unsigned int _Mode>

template<typename DerivedU >

SparseSelfAdjointView & Eigen::SparseSelfAdjointView< MatrixType, _Mode >::rankUpdate	(	const SparseMatrixBase< DerivedU > &	u,
		const Scalar &	alpha = `Scalar(1)`
	)

Perform a symmetric rank K update of the selfadjoint matrix *this: $this = this + \alpha ( u u^* )$ where u is a vector or matrix.

Returns: a reference to *this

To perform $this = this + \alpha ( u^* u )$ you can simply call this function with u.adjoint().

◆ twistedBy()

template<typename MatrixType , unsigned int _Mode>

SparseSymmetricPermutationProduct< _MatrixTypeNested, Mode > Eigen::SparseSelfAdjointView< MatrixType, _Mode >::twistedBy ( const PermutationMatrix< Dynamic, Dynamic, StorageIndex > & perm ) const

inline

Returns: an expression of P H P^-1

Returns: an expression of the matrix product between a sparse matrix lhs and a sparse self-adjoint matrix rhs.

Note that there is no algorithmic advantage of performing such a product compared to a general sparse-sparse matrix product. Indeed, the SparseSelfadjointView operand is first copied into a temporary SparseMatrix before computing the product.
