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.
Reimplemented in Eigen::SuperILU< _MatrixType >, and Eigen::SuperLU< _MatrixType >.
void Eigen::SuperLUBase< _MatrixType, Derived >::compute | ( | const MatrixType & | matrix | ) | [inline] |
Computes the sparse Cholesky decomposition of matrix
ComputationInfo Eigen::SuperLUBase< _MatrixType, Derived >::info | ( | ) | const [inline] |
Reports whether previous computation was successful.
Success
if computation was succesful, NumericalIssue
if the matrix.appears to be negative. superlu_options_t& Eigen::SuperLUBase< _MatrixType, Derived >::options | ( | ) | [inline] |
