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.

Yes, what i mean is just to make all points connected to each other.

As shown in figure, how can we make all points has an edges to connect to others?

Without changing the x value?

x = [1 8 10 12 15 16 24];

I try to use "UseGravity" and it not function.

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.
