I’m sorry but I’m really struggling to get this done. Would you be so kind and show me how it’s done? I really want to make it with a For Each Loop and at the end I need the index of the one vector that gives the smallest distance. That vector with the smallest distance is going the be the next center point and I need the index to get it from the make array list… You would do me a real favor if you could spare the time… I keep on trying in the mean time…
