— Function File: [idx, p] = tsearchn (x, t, xi)

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