Hello, I have been waiting for a new response, and I have been trying to figure it out myself but I ended up with an insucces. Can anyone please tell me how to generate a number of circles without them being on top of each other, or how to take each line from a vector? What I have been trying to do is that: -I have been trying to take each line and to compare it with the next one, so if the difference between one of the elements is 1, that means they are neighbours. Let's take an example: rc=[ 100 67; 100 68; 100 74; ...] My question is how to put each value into a variable, or something like this? I am open minded, because I realise that there might be an easier way, but I am not aware of it. Thank you!
