Detailed Description

Abstract strategy for solving the Moore-Spence pitchfork equations.

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

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

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