23 ## Produce a simple comet style animation along the trajectory provided by |
| 11382 | 24 ## the input coordinate vectors (@var{x}, @var{y}), where @var{x} will default |
| 25 ## to the indices of @var{y}. | |
| 26 ## | |
| 27 ## The speed of the comet may be controlled by @var{p}, which represents the | |
| 28 ## time which passes as the animation passes from one point to the next. The | |
| 29 ## default for @var{p} is 0.1 seconds. | |
| 30 ## | |
| 31 ## If @var{ax} is specified the animation is produced in that axis rather than | |
| 32 ## the @code{gca}. | |
