## ◆ analyzePattern()

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.

factorize()

## ◆ compute()

template<typename MatrixType_ , typename Derived >
 void Eigen::SuperLUBase< MatrixType_, Derived >::compute ( const MatrixType & matrix )
inline

Computes the sparse Cholesky decomposition of matrix

## ◆ info()

template<typename MatrixType_ , typename Derived >
 ComputationInfo Eigen::SuperLUBase< MatrixType_, Derived >::info ( ) const
inline

Reports whether previous computation was successful.

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

## ◆ options()

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.
