I have two sets of dots (x,y coordinates) and I'd like to figure out if there's a way to find out if the second set of dots is (more or less) "close" to the first one.
I may plot these two sets in two functions, but I don't know a way to tell if they are in some way similar.
Basically, what I have to do is:
- collect some sets of data (sets of dots) as references for future classification;
- collect one more set of data (this one is an "unknown" set);
- compare the last set data to the ones collected before and see if it is somehow similar to the previous ones.
What I'm missing now is the third point: what is a way to "compare" these sets of data?
