2dsearchn
Purpose n-D nearest point search
Syntax k = dsearchn(X,T,XI)
k = dsearchn(X,T,XI,outval)
k = dsearchn(X,XI)
[k,d] = dsearchn(X,...)
dsearchn
Description k = dsearchn(X,T,XI) returns the indices k of the closest points in X 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. T is a numt-by-n+1 matrix, a
tessellation of the data X generated by delaunayn. The output k is a column
vector of length p.
k = dsearchn(X,T,XI,outval) returns the indices k of the closest points in X
for each point in XI, unless a point is outside the convex hull. If XI(J,:) is
outside the convex hull, then K(J) is assigned outval, a scalar double. Inf is
often used for outval. If outval is [], then k is the same as in the case
k = dsearchn(X,T,XI).
k = dsearchn(X,XI) performs the search without using a tessellation. With
large X and small XI, this approach is faster and uses much less memory.
[k,d] = dsearchn(X,...) also returns the distances d to the closest points. d
is a column vector of length p.
