I have an iterative workflow where a distance matrix is calculated using the Distance Matrix Calculate node. At each new iteration there are only few new data points, because most of them came from older iterations. Is there a way to avoid re-calculating all the distances of the old points at each iteration?
I can save the distance matrix but then I don’t know how to extend it with the new data points, calculating only the distances between the new data points and the old ones (and of course between the new data points themselves). I think to a sort of “distance matrix extension/concatenation”. Is this possible?
Thanks in advance for any hint.
