How to plot DAG with digraph function

I am trying to run digraph function on Matlab 7 but it shows undefined function. is it required any higher function? I have also tried it on Matlab 2013 but it is not working. I have given below the code as below

s = [1 2 1]; t = [2 3 3]; G = addedge(G,s,t); please respond as early possible. sunil Arora

Hi Sunil,

your code fragment seems to be missing the initialization of the digraph. You would also want to add a plot-command. How about this:

s = [1 2 1];
t = [2 3 3];
G = digraph();
G = G.addedge(s,t);
G.plot();

I'm not sure I understood your answer correctly, but I think you also wanted to know which was the earliest release that includes the digraph function. The first release to include digraph is MATLAB release 2015b. Is that what you needed?
