int Pliris::SetLHS (  Epetra_MultiVector *  X  )

Pliris LHS Set. Associates an already defined Epetra_MultiVector (or Epetra_Vector) as the initial guess and location where the solution will be return.

int Pliris::SetMatrix (  Epetra_SerialDenseVector *  A  )

Pliris Matrix Set. Associates an already defined Epetra_SerialDenseVector as the matrix (column ordered) of the linear system.

int Pliris::SetMatrix (  Epetra_Vector *  A  )

Pliris Matrix Set. Associates an already defined Epetra_Vector as the matrix (column ordered) of the linear system.

int Pliris::SetRHS (  Epetra_MultiVector *  B  )

Pliris RHS Set. Associates an already defined Epetra_MultiVector (or Epetra_Vector) as the right-hand-side of the linear system.

int Pliris::Solve (  int *  permute, int *  num_rhs )

Pliris Solve. Parameters: permute(In)  -- permutation matrix num_rhs(In)  -- factor and solve time in seconds \ Note that the matrix has been previously factored by Factor \ The RHS has been set by SetRHS(Epetra_MultiVector * B) \ On output the result is in the RHS
