Detailed Description

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

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

Parameters:
MatrixTypethe type of the dense matrix storing the coefficients
UpLocan 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.

SparseSparseProduct<typename OtherDerived::PlainObject, OtherDerived> Eigen::SparseSelfAdjointView< MatrixType, UpLo >::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.

)

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().
