Member Function Documentation

◆ analyzePattern()

template<typename _MatrixType, int _UpLo, typename _Ordering>
void Eigen::SimplicialCholesky< _MatrixType, _UpLo, _Ordering >::analyzePattern ( const MatrixType &  a)
inline

Performs a symbolic decomposition on the sparcity of matrix.

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

factorize()

◆ compute()

template<typename _MatrixType, int _UpLo, typename _Ordering>
SimplicialCholesky& Eigen::SimplicialCholesky< _MatrixType, _UpLo, _Ordering >::compute ( const MatrixType &  matrix)
inline

Computes the sparse Cholesky decomposition of matrix

◆ factorize()

template<typename _MatrixType, int _UpLo, typename _Ordering>
void Eigen::SimplicialCholesky< _MatrixType, _UpLo, _Ordering >::factorize ( const MatrixType &  a)
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.
