Detailed Description

template<typename _MatrixType, bool IsStrSym>
class Eigen::PastixLU< _MatrixType, IsStrSym >

Interface to the PaStix solver.

Sparse direct LU solver based on PaStiX library.

This class is used to solve the linear systems A.X = B via the PaStix library. The matrix can be either real or complex, symmetric or not.

See also: TutorialSparseDirectSolvers

This class is used to solve the linear systems A.X = B with a supernodal LU factorization in the PaStiX library. The matrix A should be squared and nonsingular PaStiX requires that the matrix A has a symmetric structural pattern. This interface can symmetrize the input matrix otherwise. The vectors or matrices X and B can be either dense or sparse.

Template Parameters

_MatrixType	the type of the sparse matrix A, it must be a SparseMatrix<>
IsStrSym	Indicates if the input matrix has a symmetric pattern, default is false NOTE : Note that if the analysis and factorization phase are called separately, the input matrix will be symmetrized at each call, hence it is advised to symmetrize the matrix in a end-user program and set `IsStrSym` to true
