Detailed Description

Abstract strategy for solving the Moore-Spence turning point equations.

This class provides an abstract interface for solver strategies to solve the Moore-Spence turning point Newton system:

$\begin{bmatrix} J & 0 & f_p \\ (Jv)_x & J & (Jv)_p \\ 0 & \phi^T & 0 \end{bmatrix} \begin{bmatrix} X \\ Y \\ z \end{bmatrix} = \begin{bmatrix} F \\ G \\ h \end{bmatrix}.$

After instantiating a solver (via LOCA::TurningPoint::MooreSpence::SolverFactory), the linear system is set up by setBlocks() and can then be solved by solve().
