Transform to form the explicit transpose of a Epetra_RowMatrix.
Epetra_CrsMatrix * CreateTransposeLocal(OriginalTypeRef orig)
Local-only transpose operator. Don't use this unless you're sure you know what you're doing.
NewTypeRef operator()(OriginalTypeRef orig)
Transpose Transform Operator.
void ReleaseTranspose()
Release the pointer to TransposeMatrix_ (so you can take the matrix out w/o worring about deallocatio...
RowMatrix_Transpose(Epetra_Map *TransposeRowMap=0, bool IgnoreNonLocalCols=false)
Constructor.
EpetraExt::BlockCrsMatrix: A class for constructing a distributed block matrix.
