The base class for the direct and incomplete LU factorization of SuperLU.
void 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 SuperLU< _MatrixType >, and SuperILU< _MatrixType >.
Referenced by SuperILU< _MatrixType >::analyzePattern(), and SuperLU< _MatrixType >::analyzePattern().
void compute | ( | const MatrixType & | matrix | ) | [inline] |
Computes the sparse Cholesky decomposition of matrix
ComputationInfo 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& options | ( | ) | [inline] |
