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.
