Error using digraph (line 214) Adjacency matrix must be square.

Hi, I'm trying to create a biograph that will allow me to find the shortest path from one node to another, but when I try to create the biograph I keep getting an error.

    Error using digraph (line 214) Adjacency matrix must be square

This is my code that I'm using,

W = [1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ] 
DG = sparse ([1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 2 3 8 9 4 3 18 17 1 2 3 4 5 8 9 18 17 20 19 18 13 12 17 16 3 4 23 23 23 23 22 22 22 22], [2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1 19 18 13 12 7 8 13 14 19 18 13 8 7 12 11 14 15 2 3 8 9 10 13 14 7 6 1 2 19 20 9 10 11 12], W ) 
h =view(biograph(DG))

Any help would be appreciated
