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

inline

Performs a symbolic decomposition on the sparcity of matrix.

This function is particularly useful when solving for several problems having the same structure.

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 has the same sparcity than the matrix on which the symbolic decomposition has been performed.

template<typename _MatrixType, int _UpLo, typename Derived>

ComputationInfo Eigen::CholmodBase< _MatrixType, _UpLo, Derived >::info ( ) const

inline

Reports whether previous computation was successful.

Returns: Success if computation was succesful, NumericalIssue if the matrix.appears to be negative.

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.
