create adjacency matrix of non-integer values

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)
