pointset - a N by D double matrix
containing the coordinates of the point set, organized as
N points of dimension D
atria - output of (cf. Section 6.13)nn_prepare for pointset
query_points - a R by D double matrix
containing the coordinates of the query points, organized
as R points of dimension D
query_indices - query points are taken out of the
pointset, query_indices is a vector of length R
which contains the indices of the query points
r - range or search radius (r
0)
exclude - in case the query points are taken out of the
pointset, exclude specifies a range of indices which are
omitted from search. For example if the index of the query point
is 124 and exclude is set to 3, points with indices 121
to 127 are omitted from search. Using exclude = 0 means:
exclude self-matches
Output arguments:
count - a vector of length R contains the number
of points within distance r to the corresponding query
point
neighbors - a Matlab cell structure of size R by 2
which contains vectors of indices and vectors of
distances to the neighbors for each given query point.
This output argument can not be stored in a standard
Matlab matrix because the number of neighbors within
distance r is not the same for all query points. The
vectors if indices and distances for one query point have
exactly the length that is given in count. The values in
the distances vectors are not sorted..
