Detailed Description

An implementation of a class for an $n^{th}$ -order ODE BVP defined by.

${\underline f}^\prime (x) = {\underline R}( {\underline f}(x), x )\,,$

subject to Dirichlet conditions defined at $x = x_{left}$ or $x_{right}$ for some components of ${\underline f}(x)$ . The system is solved by applying Newton iteration, with the intermediate problem:

${\underline g}^\prime (x) - \frac{\partial {\underline R}}{\partial \underline f} \Big \vert_{\underline F} \,\,{\underline g}(x) = {\underline R}( {\underline F}(x), x) - {\underline F}^\prime (x) \,,$

for the corrections $\underline g(x)$ to the current approximation to the solution ${\underline F}(x)$ .The numerical scheme can be run for any given distribution of nodes and can adapt the nodal positions based on residual evaluations (including both refinement and unrefinement).
