if i have data
1 2 3 4
2 3 5 6
3 5 6 7
in first row the element 1 has a connection with elements 2,3,4. And so on in remaining rows, so i want the adjacency matrix as
0 1 1 1 0 0 0
1 0 1 0 1 1 0
1 1 0 0 1 1 1
1 0 0 0 0 0 0
0 1 1 0 0 0 0
0 1 1 0 0 0 0
0 0 1 0 0 0 0

Same basic technique as in https://www.mathworks.com/matlabcentral/answers/390250-how-to-calculate-adjacency-matrix#answer_311752 which is waiting for a response from you.
A = [1 2 3 4
2 3 5 6
3 5 6 7];
[r, c, s] = find(A(:,2:end));
adj = full(sparse([r,s],[s,r],1));
