# convhulln

N-D convex hull

## Description

## Examples

## Input Arguments

## Output Arguments

## Tips

Use the

`plot`

function to plot the output of`convhulln`

in two dimensions. Use`trisurf`

or`trimesh`

to plot the output of`convhulln`

in three dimensions.For better algorithm efficiency with 2-D and 3-D input, consider using the

`convhull`

function or creating a`triangulation`

or`delaunayTriangulation`

object and using the`convexHull`

object function.

## Algorithms

`convhulln`

is based on Qhull [1]. For information, see http://www.qhull.org/. For copyright information, see http://www.qhull.org/COPYING.txt.
