| cholmod_common& Eigen::CholmodBase< _MatrixType, _UpLo, Derived >::cholmod | ( | ) | [inline] |
Returns a reference to the Cholmod's configuration structure to get a full control over the performed operations. See the Cholmod user guide for details.

| 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.

- analyzePattern()
Definition at line 275 of file CholmodSupport.h.
| ComputationInfo Eigen::CholmodBase< _MatrixType, _UpLo, Derived >::info | ( | ) | const [inline] |
Reports whether previous computation was successful.
- Returns:
Successif computation was succesful,NumericalIssueif 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.
