Hello guys ! First of all sorry for my bad english...
I got Matlab2016, and i would like to know if is possible enlarge a node in a graph. Is there some particular function or not?
My idea is to enlarge one node based on the number of link that it has.. if one node has got many link is BIG, if it has few link is SMALL.
can you help me please?
really thanks to you :D

highlight function may be the one you are looking for. highlight: Highlight nodes and edges in plotted graph The following is one of the examples from the page above with a slight modification:
n = 8;
A = delsq(numgrid('S',n+2));
G = graph(A,'OmitSelfLoops');
p = plot(G);
highlight(p,36,'MarkerSize',20)
highlight(p,6,'MarkerSize',5)
You can make a specific node bigger. Hope this helps.

Really thank for this help!! Only one question... is maybe possible that the program understand automatically which node enlarge? Or i've to do this manually?
For example... how can i expand one node with 20 link and differentiate it from another one that got only 1 link?

I thought you wanted do this manually.
degree find the number of links of each node. I think you can make use of this. See Degree of graph nodes.
For example, setting the output of degree to MarkerSize property would enlarge the node to the size which is a function of the number of links. Below, numlinks is squared so that the effect is more visible.
n = 8;
A = delsq(numgrid('S',n+2));
G = graph(A,'OmitSelfLoops');
p = plot(G);
numlinks = degree(G);
p.MarkerSize = numlinks.^2;
You can modify numlinks as you want. Say, if you want to enlarge a node with 2 links:
n = 8;
A = delsq(numgrid('S',n+2));
G = graph(A,'OmitSelfLoops');
p = plot(G);
numlinks = degree(G);
Node2enlarge = find(numlinks == 2);
highlight(p, Node2enlarge);
