| 0 | 1 % Calls F(t) repeatedly |
| 2 % Should there be a Fsetup and a F, two function, to allow creating a plot and then updating it? | |
| 3 % F takes the time to generate the frame for and returns the actual time for the generated frame. | |
| 4 % t = F(t_r) is a function that paints a frame for time t. t is the closest time <=t_r | |
| 5 % it will be called for increasnig t. | |
| 6 | |
| 7 %Todo: make it catch up and produce warnings if it lags behind? Instead of just requesting the next target time | |
| 8 function animate(F, t, tend, time_modifier , frame_rate) | |
| 9 if ~exist('time_modifier') | |
| 10 time_modifier = 1; | |
| 11 end | |
| 12 | |
| 13 if ~exist('frame_rate') | |
| 14 frame_rate = 30; | |
| 15 end | |
| 16 | |
| 17 frame_time = 1/frame_rate; | |
| 18 dt = frame_time*time_modifier; | |
| 19 | |
| 20 animation_start = tic(); | |
| 21 t = F(t); | |
| 22 while t < tend | |
| 23 t = F(t + dt); | |

| 25 t_left = t/time_modifier-toc(animation_start); | |
| 26 | |
| 27 pause(t_left) | |
