Hi,
I have two 3D data set. I found the centroids of data by k-means with clustering. Then i plotted the two data set as given below.
I need to find the closest distance between two point in varied data set. (closest distances between x and o)
I think euclidian method may be most suitable for 3D data but how can i apply it to my data.
And can i draw arrows between x and o
