22 ## Compute N-dimensional Voronoi facets. The input matrix @var{pts}
23 ## of size [n, dim] contains n points in a space of dimension dim.
24 ## @var{C} contains the points of the Voronoi facets. The list @var{F}
25 ## contains, for each facet, the indices of the Voronoi points.
27 ## An optional second argument, which must be a string or cell array of strings,
28 ## contains options passed to the underlying qhull command.
29 ## See the documentation for the Qhull library for details

50 error ("voronoin: number of points must be greater than their dimension");
