Moore-Spence Hopf solver strategy based on "Salinger" bordering. This is the classic 5-solve Hopf bordering method.
This class solves the Moore-Spence Hopf Newton equations:
![\[ \begin{bmatrix} J & 0 & 0 & 0 & f_p \\ (Jy-wBz)_x & J & -wB & -Bz & (Jy-wBz)_p \\ (Jz+wBy)_x & wB & J & By & (Jz+wBy)_p \\ 0 & \phi^T & 0 & 0 & 0 \\ 0 & 0 & \phi^T & 0 & 0 \end{bmatrix} \begin{bmatrix} X \\ Y \\ Z \\ \omega \\ \lambda \end{bmatrix} = \begin{bmatrix} F \\ G \\ H \\ u \\ v \end{bmatrix}. \]](form_460.png)
via the following block elimination scheme:
![\[ \begin{split} J [A \; b] &= [F \; f_p] \\ \begin{bmatrix} J & -wB \\ wB & J \end{bmatrix} \begin{bmatrix} C & e & g \\ D & f & h \end{bmatrix} &= \begin{bmatrix} G - (Jy-wBz)_x A & (Jy-wBz)_p - (Jy-wBz)_x b & -Bz \\ H - (Jz+wBy)_x A & (Jz+wBy)_p - (Jy-wBz)_x b & By \end{bmatrix} \\ \lambda &= \frac{(\phi^T h)(\phi^T C-u)-(\phi^T g)(\phi^T D-v)} {(\phi^T h)(\phi^T e)-(\phi^T g)(\phi^T f)} \\ \omega &= \frac{\phi^T D - v - (\phi^T f)\lambda}{\phi^T h} \\ X &= A - b \lambda \\ \begin{bmatrix} Y \\ Z \end{bmatrix} &= \begin{bmatrix} C \\ D \end{bmatrix} - \begin{bmatrix} e \\ f \end{bmatrix}\lambda - \begin{bmatrix} g \\ h \end{bmatrix}\omega \end{split} \]](form_461.png)
