NOX pure abstract interface to a "group"; i.e., a solution vector and the corresponding F-vector, Jacobian matrix, gradient vector, and Newton vector.
This class is a member of the namespace NOX::Abstract.
The user should implement their own concrete implementation of this class or use one of the implementations provided by us. Typically the implementation is also tied to a particular NOX::Abstract::Vector implementation.
The computation of, say, the Newton direction in computeNewton() may fail in many different ways, so we have included a variety of return codes to describe the failures. Of course, we also have a code for success.
