MATLAB: Graph how to get every connected nodes from this specific graph

Question

Hi, I have graph that is described in this way

U = {[1 3],[1 4],[1 5],[5 2]};

and it looks like this

How can i get two arrays, s array would show first node and t array would show accordingly the next node connected to it.

Example below.

s[1 1 1 2 3 4 5 5]
t[3 4 5 5 1 1 1 2]

Thanks in advance.

Answer 1

Hi,

you find s and t by using:

U = {[1 3],[1 4],[1 5],[5 2]};
A = cat(1,U{:});
s = A(:,1);
t = A(:,2);

Best regards
