Detailed Description
This simulates a simple 2nd order ODE with mixed boundary conditions.
Solves:
\[ \mathrm D u(y)\,-\,4\, u(y)\;=\; 1 \; - \; y^2, \]
with boundary conditions:
\begin{align*} u(-1) \,+\, 4\,[\mathrm D u(\cdot)](-1)\;&=\; 2,\\ u(+1) \,-\, 5\,[\mathrm D u(\cdot)](+1)\;&=\; 3. \end{align*}
where \( \mathrm D = \mathrm d/\mathrm d y \). Solving by entering the forcing in physical-space, so solution is returned in physical space.
