filename = 'test.txt';
%part 1: create some demonstration data to work with
s = randi(9, 15, 1);
t = randi(9, 15, 1);
writematrix([s,t], filename);
%part 2: read the demonstration data:
st = readmatrix(filename);
s = st(:,1);
t = st(:,2);
%part 3: create the graph:
G = graph(s, t);
%part 4: draw the graph:
plot(G)
It look s to me as if readmatrix() does in fact work.
