No i want the code to import a file that contains a matrix in order to draw a graph

[Walter Roberson]

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.
