Hello, i created a script which creates N amount of random vectors (with random set of x and y coordinates), where you can decide how many you want to be created. Is there a way to sort them in an ascending fasion via the x coordiantes and if x coordinates are the same via the y coordinate? I cant seem to make it work.

How can i sort these vectors?

N = input('Wieviele Vektoren wollen Sie erzeugen?:');
Asize = [50,50];
[Ix,Iy] = ind2sub(Asize,randperm(prod(Asize),N));
I = [Ix',Iy']

Have a look at the help and documentation of the function sortrows. Also (if this is a educational programming task) read the help and documentation of the function sort and make use of that in a step-by-step algorithm.
