This question displays a randomly generated graph with nodes and edges. Students are asked to provide the corresponding adjacency matrix. Matrix entries that are left blank are considered as zero. Students can get partial credit for each correct matrix entry.

Matrix component input: random graph

What is the adjacency matrix ${\bf A}$ corresponding to the graph below?

0 0 0->0 1 1 0->1 2 2 1->2 3 3 2->3

Hint: zero entries can be left blank.

Correct answer

$\mathbf{A} = $ $\begin{bmatrix} 1 & 0 & 0 & 0\\ 1 & 0 & 0 & 0\\ 0 & 1 & 0 & 0\\ 0 & 0 & 1 & 0\\\end{bmatrix}$
