| 9 % Prints some info about the discretisation | |

| 11 | |
| 12 % Return the number of DOF | |
| 13 n = size(obj) | |
| 14 | |
| 15 % Returns a timestepper for integrating the discretisation in time | |
| 16 % method is a string that states which timestepping method should be used. | |
| 17 % The implementation should switch on the string and deliver | |
| 18 % the appropriate timestepper. It should also provide a default value. | |
| 19 % time_align is a time that the timesteps should align with so that for some | |
| 20 % integer number of timesteps we end up exactly on time_align | |
| 21 ts = getTimestepper(obj,method,time_align) %% ??? | |
| 22 | |
| 23 % Sets up movie recording to a given file. | |
| 24 % saveFrame is a function_handle with no inputs that records the current state | |
| 25 % as a frame in the moive. | |
| 26 saveFrame = setupMov(obj, file) | |
| 27 | |
| 28 % Sets up a plot of the discretisation | |
| 29 % update is a function_handle accepting a timestepper that updates the plot to the | |
| 30 % state of the timestepper | |
| 31 [update,hand] = setupPlot(obj) | |
