◆ factorize()

template<typename _MatrixType, int _UpLo, typename Derived>

void Eigen::CholmodBase< _MatrixType, _UpLo, Derived >::factorize ( const MatrixType & matrix )

inline

Performs a numeric decomposition of matrix

The given matrix must have the same sparsity pattern as the matrix on which the symbolic decomposition has been performed.

◆ setShift()

template<typename _MatrixType, int _UpLo, typename Derived>

Derived& Eigen::CholmodBase< _MatrixType, _UpLo, Derived >::setShift ( const RealScalar & offset )

inline

Sets the shift parameter that will be used to adjust the diagonal coefficients during the numerical factorization.

During the numerical factorization, an offset term is added to the diagonal coefficients:
d_ii = offset + d_ii

The default is offset=0.

Returns: a reference to *this.
