[Haskell-cafe] Is the following implemented by a sparse matrix representation? type Graph n w = Array (n, n) (Maybe w)

Looks like the graph is represented by an adjacency matrix, where the
element at (a, b) tells you whether there is an edge from node a to node
b with weight x or not by having the value (Just x) or Nothing,
Whether the matrix is sparse depends on the data, i.e. how many edges
are in the graph.
But perhaps I misunderstood your question.
