tsearch

Search for enclosing Delaunay triangle

Syntax

T = tsearch(x,y,TRI,xi,yi)

Description

T = tsearch(x,y,TRI,xi,yi) returns an index into the rows of TRI for each point in xi,yi. The tsearch command returns NaN for all points outside the convex hull. Requires a triangulation TRI of the points x,y obtained from delaunay.

Note    tsearch is based on qhull [1]. 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.
