annotate +scheme/error2d.m @ 815:fae41958af4f feature/burgers1d
Add support for artificial viscosity to the 1d burgers scheme.
- Add support for artificial viscosity by parametrizing the discretization operator and boundary closure on the viscosity.
- Add a time stepper which evaluates and updates the residual viscosity of the solution.

2 % If v1 and v2 are more complex types, something like grid functions... Then we may use .getVectorFrom here! |
