Hello
I have a fuzzy edge list that I want to convert it to adjacency matrix. I tried using sparse matrix from this thread in stackoverflow. But I get error. This is a part of my edge list.
A B Value
0 3539 9.22
0 6281 7.24
0 13033 7.55
0 19654 9.14
0 36825 8.84
0 63309 8.26
1 12855 9.42
1 22542 8.10
1 66857 8.77
1 72969 9.58
1 7281 4.88
1 33392 4.62
1 33393 3.46
1 33394 3.22
1 59140 2.37
1 75011 4.77
2 12717 7.81
4 14870 8.95
....
How can I create adjacency from this?
Thanks

Are A and B intended to be node numbers, with the lowest one numbered 0? MATLAB does not permit 0 to be used as an index so you would need to add one to A and B to construct the sparse matrix.
adjacency = sparse(A+1, B+1, Value)
