Amesos_Superlu: Amesos interface to Xioye Li's SuperLU 3.0 serial code. Class Amesos_Superlu solves the linear systems of equations A X = B, where A is defined as an Epetra_RowMatrix, and X and B are two Epetra_MultiVector's. C++ includes: Amesos_Superlu.h

__init__(self, LinearProblem LinearProblem) -> Superlu Amesos_Superlu::Amesos_Superlu(const Epetra_LinearProblem &LinearProblem) Amesos_Superlu Constructor. Creates an Amesos_Superlu instance, using an Epetra_LinearProblem, passing in an already- defined Epetra_LinearProblem object. Note: The operator in LinearProblem must be an Epetra_RowMatrix.
