Detailed Description

Decorator class that creates a W (Jacobian) operator using Matrix-Free directional derivatives.

This class takes a model evaluator that supports a residual calculation, and adds support for the W matrix as an epetra_operator.

This class is the ModelEvaluator version of NOX_Epetra_MatrixFree. One difference, is that it supports time-dependent problems when x_dot != null or x_dotdot !- null, and using alpha, beta, and omega.

The documentation for this class was generated from the following files:

Piro_Epetra_MatrixFreeDecorator.hpp
Piro_Epetra_MatrixFreeDecorator.cpp
