Detailed Description

Interface to underlying groups for homotopy calculations.

This abstract class provides an interface for a homotopy technique for solving nonlinear equations. See LOCA::Homotopy::Group for a description of the technique used. This class provides a single pure virtual method, augmentJacobianForHomotopy(), which scales the diagonal of the Jacobian by a constant times the identity matrix.
