Fix this and give output with more digits. --- diff --git a/examples/step-3/doc/results.dox b/examples/step-3/doc/results.dox index e2054cee20..a39a00addc 100644 --- a/examples/step-3/doc/results.dox +++ b/examples/step-3/doc/results.dox @@ -203,15 +203,15 @@ suggestions: the following result: - - - - - - - - - + + + + + + + + +

Again, the difference between two adjacent values goes down by about a factor of four, indicating convergence as ${\cal O}(h^2)$.
