Computes the sparse Cholesky decomposition of matrix
void factorize |
( |
const MatrixType & |
matrix | ) |
|
|
inline |
Reports whether previous computation was successful.
- Returns
Success
if computation was succesful, NumericalIssue
if the matrix.appears to be negative.
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.
