convhull See Also convhulln, delaunay, plot, polyarea, voronoi Reference [1] Barber, C. B., D.P. Dobkin, and H.T. Huhdanpaa, "The Quickhull Algorithm for Convex Hulls," ACM Transactions on Mathematical Software, Vol. 22, No. 4, Dec. 1996, p. 469-483. Available in HTML format at http://www.acm.org/ pubs/citations/journals/toms/1996-22-4/p469-barber/ and in PostScript format at ftp://geom.umn.edu/pub/software/qhull-96.ps. 2-332 [2] National Science and Technology Research Center for Computation and Visualization of Geometric Structures (The Geometry Center), University of Minnesota. 1993.
2convhulln Purpose n-D convex hull Syntax K = convhulln(X) [K,v] = convhulln(X) convhulln Description K = convhulln(X) returns the indices K of the points in X that comprise the facets of the convex hull of X. X is an m-by-n array representing m points in n-D space. If the convex hull has p facets then K is p-by-n. [K,v] = convhulln(X) also returns the volume v of the convex hull. Note convhulln is based on qhull [2]. For information about qhull, see http://www.geom.umn.edu/software/qhull/. For copyright information, see http://www.geom.umn.edu/software/download/COPYING.html. Visualization Plotting the output of convhulln depends on the value of n: • For n = 2, use plot as you would for convhull. • For n = 3, you can use trisurf to plot the output. The calling sequence is K = convhull(X); trisurf(K,(X(:,1),X(:,2),X(:,3)) For more control over the color of the facets, use patch to plot the output. For an example, see “Tessellation and Interpolation of Scattered Data in Higher Dimensions” in the MATLAB documentation. • You cannot plot convhulln output for n > 3.
