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
MatrixTypethe type of the dense matrix storing the coefficients
Modecan 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.

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().
