tsearch
Search for enclosing Delaunay triangle
T = tsearch(x,y,TRI,xi,yi)
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.

dsearch Search for nearest point
