Detailed Description
This solves the problem for a block matrix operator system.
The eigenvalue problem is given by:
\[ \left[ \begin{array}{cc} \frac{1}{4} \mathrm D^2 + 2y & 1.0 \\ \sin (2y) & \frac{1}{4}\mathrm D^2 \end{array} \right] \left[ \begin{array}{c} u \\ v \end{array} \right] \;=\; \lambda \left[ \begin{array}{c} u \\ v \end{array} \right], \]
with boundary conditions:
\[ u(\pm 1) \;=\; v(\pm 1) \;=\; 0. \]
where \( \mathrm D = \mathrm d/\mathrm d y \).
