Detailed Description

Implemenatation of the NOX::Abstract::Vector class for extended vectors comprised of an arbitrary number of vectors and scalars.

Many continuation and bifurcation calculations can be viewed as the solution to an extended set of equations. For example, calculating a turning point can be viewed as computing a solution to $G(z) = 0$ where $z = [x, n, p]\in\Re^{2n+1}$ and

$G(z) = \left[ \begin{array}{c} F(x,p) \\ Jn \\ n^Tn-1 \end{array} \right]$

The extended vector $z$ is comprised of the two vectors $x$ and $n$ as well as the scalar $p$ . This class provides an implementation of the NOX::Abstract::Vector interface for such extended vectors. It stores an array of pointers to NOX::Abstract::Vector's as well as an array of scalars using the STL vector class.

The implementations of the NOX::Abstract::Vector methods are defined in terms of the implementations of each stored abstract vector.

generate an extended multi-vector

Extended vectors derived from this class should implement this method and return a multivector of the appropriate type so that the createMultiVectors method returns a multivector of the appropriate type.

Reimplemented in LOCA::Hopf::ComplexVector, LOCA::Hopf::MooreSpence::ExtendedVector, LOCA::MultiContinuation::ExtendedVector, LOCA::Pitchfork::MooreSpence::ExtendedVector, and LOCA::TurningPoint::MooreSpence::ExtendedVector.
