# delaunayn

Computes the ND Delaunay triangulation.

## Syntax

h = delaunayn(pts)

h = delaunayn(pts,options)

## Inputs

pts
The coordinate matrix.
Each row contains the coordinates of a point.
Type: double
Dimension: matrix
options
The Qhull options. A string with options separated by spaces, or a cell of strings. Omit or use [] for the default. For no options, use an empty string.
Defaults:
'Qt Qbb Qc Qz'
For less than four dimensions.
'Qt Qbb Qc Qx'
For four or more dimensions. See Comments.

## Outputs

T
Each row contains the indices of a simplex of the triangulation.
Dimension: matrix

## Example

Triangulate the unit cube with the center point.

x = [0.5 0 1 0 1 0 1 0 1]';
y = [0.5 0 0 1 1 0 0 1 1]';
z = [0.5 0 0 0 0 1 1 1 1]';
T = delaunayn([x, y, z])
T = [Matrix] 12 x 4
