Detailed Description

Specialization of LOCA::MultiContinuation::ExtendedGroup to natural continuation.

Natural continuation corresponds to a continuation equation $g(x,p,x_0,p_0,x^\ast,p^\ast,v,\Delta s)=0$ with $g$ given by

\[ g(x,p,x_0,p_0,x^\ast,p^\ast,v,\Delta s)= p-p_0-v_p \Delta s \]

where $v_p$ is the parameter component of the predictor direction $v$. This corresponds geometrically to constraining the nonlinear solver steps used in calculating $F(x,p)=0$ to be orthogonal to the parameter axis. The natural constraint $g$ is represented by a LOCA::MultiContinuation::NaturalConstraint object.
