[indices, bestSqDist] = nearpoints(src, dest) For each point in one set, find the nearest point in another. - src is a 3xM array of points - dest is a 3xN array of points - indices is a 1xM vector, in which each element tells which point in dest is closest to the corresponding point in src. For example, dest[indices[i]] is near src[i]. - bestSqDist is a 1xM array of the squared distance between dest[indices[i]] and src[i]. Compile the mex function with something like: mex -O nearpoints.cxx HISTORY: 2004.05.01 Dan Merget wrote it.
