hello,
This is my graph
G=[0 1 1 0 0 0;1 0 1 1 0 0; 1 0 0 1 1 0; 0 0 0 0 1 0; 0 0 0 0 0 1; 0 1 0 1 1 0];
when I apply the function neighbors
neighbors(G,active_nodes_last_round(individual));
where active_nodes_last_round(individual)=1;
I got the following error:
Undefined function 'neighbors' for input arguments of
type 'double'.
Error in IC_paper1 (line 26)
potential_infected=neighbors(G_duplicate,active_nodes_last_round(individual));
Thanks in advance

The neighbors function, in this context, requires its first input to be a graph object not an adjacency matrix. Create a graph object from your adjacency matrix by calling graph and pass the resulting object into neighbors.

If you've purchased a license for the later releases you should have received instructions on how to download and install it in an email from Mathworks. Or you could go to the "Download Products" section on the Support section of the website, or you could click on the Get MATLAB button in the upper-right corner of this page.

thanks @ steven
I installed trail ver. , and I run the code.
I created adjacancy mat. and call graph, then run code without any problem.
In fact the code is existing in a paper, it is working but the results are not satisfied.
