N-dimensional closest simplex search
Syntax
Description
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-dimensional space. XI
is a p
-by-n
matrix, representing p
points in N-dimensional 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 a p
-by-n+1
matrix. Each row of P
is the Barycentric coordinate of the corresponding point in XI
. It is useful for interpolation.
