Hi, i want to make all point has a connection to other with the following code.

x = [6 3 5 4 7 8];  
idx = randperm(length(x));
y = x(idx);
start = x(:,2);
last = x(:,(length(x)));
w=randi(100, size(x));
G = digraph(x,y,w);
G = rmedge(G, 1:numnodes(G), 1:numnodes(G)); 
plot(G,'EdgeLabel',G.Edges.Weight) ;
path = shortestpath(G, start, last);
disp(['spf = ' num2str(path)]);

The result:

Is that possible to all point include no1 & 2 connect to each other?

Thanks.

For example,

x = [1 3 4 8 9 15];

we add num 2 in x.

x1 = [x, 2];

How to add automatically the missing numbers (2,5,6,7,10,11,12,13,14) into x ?

You mean like

x = min(x) : max(x)

Or should it be assumed that 1 will always be included?

If some of the values have been excluded, how do we know that the maximum has been included?

If it were a matter of figuring out which vertices did not have any edges incident to them, then that would not be difficult... though it does still assume that the maximum is present.
