TSEARCHN N-D closest simplex search.
    T = TSEARCHN(X,TES,XI) returns the indices T of the enclosing simplex
    of the Delaunay tessellation TES for each point in XI. X is
    an m-by-n matrix, representing m points in n-D space. XI is
    a p-by-n matrix, representing p points in n-D space.  TSEARCHN returns
    NaN for all points outside the convex hull of X. TSEARCHN requires a
    tessellation TES of the points X obtained from DELAUNAYN.
  
    [T,P] = TSEARCHN(X,TES,XI) also returns the barycentric coordinate P
    of XI in the simplex TES. P is an p-by-n+1 matrix. Each row of P is the
    barycentric coordinate of the corresponding point in XI. It is useful
    for interpolation.
