% Searches for the enclosing Delaunay convex hull. For @code{@var{t} =
% delaunayn (@var{x})}, finds the index in @var{t} containing the
% points @var{xi}. For points outside the convex hull, @var{idx} is NaN.
% If requested @code{tsearchn} also returns the Barycentric coordinates @var{p}
% of the enclosing triangles.
