23 ## Plot a ribbon plot for the columns of @var{y} vs. @var{x}. The |
| 7164 | 24 ## optional parameter @var{width} specifies the width of a single ribbon |
| 25 ## (default is 0.75). If @var{x} is omitted, a vector containing the | |
| 26 ## row numbers is assumed (1:rows(Y)). If requested, return a vector | |
| 27 ## @var{h} of the handles to the surface objects. | |
