Detailed Description

$ D_{0} $ matricial representation

The differential operator $ D_{0} $ discretizes the first derivative with the second-order formula

\[ \frac{\partial u_{i}}{\partial x} \approx \frac{u_{i+1}-u_{i-1}}{2h} = D_{0} u_{i} \]

Tests:
the correctness of the returned values is tested by checking them against numerical calculations.
