 **Note**—Using this operation in dimensions greater than six is impractical because the memory required by the underlying triangulation grows exponentially with its rank.
 
 **Note**—Because this operator uses a Delaunay triangulation, it can be sensitive to scaling issues in `input`. When this occurs, you should standardize `input` to improve the results.
