get adjacent matrix from horizontal visibility Graph code.

i want to get adjacency matrix from horizontal visibility graph code. i know that reshaping dvd as 1xnumel(dvd) would get adjancency matrix 12x12 but i have to run graph code for each column by using for loop columnwise on smaller data (dvd) and get a single adjacent matrix, i am trying this so that i can also run this for large data,which gives me adjancency matrix of 1048560x1048560.

Hi Vedant Chauhan,

I understand that you are trying to find the adjacency matrix of a graph.

In MATLAB,you have the ability to get the adjacency matrix of a graph using "adjacency" function.You can follow the below given example to resolve the issue.

A = [0 5 3 0;0 0 1 2; 0 0 0 11; 0 0 0 0];
G = graph(A,'upper');
B = adjacency(G);

For a comprehensive understanding of the "adjacency" function in MATLAB, please refer to the provided documentation below.
