Adjacency matrix formation from n*n matrix

I have a matrix

A= [ 1 2

1 3

1 4

2 3

2 4

3 4 ]

and another weight matrix W= [4, 2, 3, 1] i.e weight of the first pair of A is 4, second pair is 2 etc.

i want to output in the form

edgeData = [1 2 4; 2 3 2; 1 3 3; 1 4 1];

Answer 1

[Guillaume]

edgeData = [A, W(:)]

Note that this is not an adjacency matrix.

Also, you may actually want to input that into a graph or digraph:

G = graph(A(:, 1), A(:, 2), W(:))
