Detailed Description

The base class for the direct and incomplete LU factorization of SuperLU.

Member Function Documentation

template<typename _MatrixType, typename Derived>

void Eigen::SuperLUBase< _MatrixType, Derived >::analyzePattern ( const MatrixType & )

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, typename Derived>

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

inline

Reports whether previous computation was successful.

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

template<typename _MatrixType, typename Derived>

superlu_options_t& Eigen::SuperLUBase< _MatrixType, Derived >::options ( )

inline

Returns: a reference to the Super LU option object to configure the Super LU algorithms.
