Detailed Description

Abstract strategy for solving the Moore-Spence Hopf equations.

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

\[ \begin{bmatrix} J & 0 & 0 & 0 & f_p \\ (Jy-wBz)_x & J & -wB & -Bz & (Jy-wBz)_p \\ (Jz+wBy)_x & wB & J & By & (Jz+wBy)_p \\ 0 & \phi^T & 0 & 0 & 0 \\ 0 & 0 & \phi^T & 0 & 0 \end{bmatrix} \begin{bmatrix} X \\ Y \\ Z \\ \Omega^T \\ \Lambda^T \end{bmatrix} = \begin{bmatrix} F \\ G \\ H \\ U^T \\ V^T \end{bmatrix}. \]

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