Computing convergence rates
Frequent assumption on the relation between the numerical error \( E \) and
some discretization parameter \( \Delta t \):
$$
\begin{equation}
E = C\Delta t^r,
\tag{1}
\end{equation}
$$
- Unknown: \( C \) and \( r \).
- Goal: estimate \( r \) (and \( C \)) from numerical experiments
