Detailed Description

Amesos_EpetraBaseSolver: A generic implementation of Amesos_BaseSolver for Epetra Matrices.

Amesos_EpetraBaseSolver is a concrete implementation of Amesos_BaseSolver for Epetra_RowMatrix, Epetra_Crsmatrix, and Epetra_VbrMatrix. The class furnishes a GetRow function, which operates in Copy mode for Epetra_RowMatrix, and in View mode (hence faster) for Epetra_CrsMatrix and Epetra_VbrMatrix.

Member Function Documentation

bool Amesos_EpetraBaseSolver::MatrixShapeOK (   )  const [virtual]

Returns true if the solver can handle this matrix shape. Returns true if the matrix shape is one that the underlying sparse direct solver can handle. Classes that work only on square matrices should return false for rectangular matrices. Classes that work only on symmetric matrices whould return false for non-symmetric matrices. Implements Amesos_BaseSolver.

int Amesos_EpetraBaseSolver::SetMatrixProperty (  const int  property  )  [inline]

Set the matrix property (unsymmetric, SPD, general symmetric). Set the matrix property as follows: 0 : general unsymmetric matrix; 1 : SPD; 2 : general symmetric matrix.
