struct | PEXSI::ULComparator |
struct | PEXSI::GridType |
GridType is the PSelInv way of defining the grid. More... | |
struct | PEXSI::SuperNodeType |
SuperNodeType describes mapping between supernode and column, the permutation information, and potentially the elimination tree (not implemented here). More... | |
struct | PEXSI::LBlock< T > |
LBlock stores a nonzero block in the lower triangular part or the diagonal part in PSelInv. More... | |
struct | PEXSI::UBlock< T > |
UBlock stores a nonzero block in the upper triangular part in PSelInv. More... | |
class | PEXSI::PMatrix< T > |
PMatrix contains the main data structure and the computational routine for the parallel selected inversion. More... | |
