`scipy.sparse.csgraph.``csgraph_masked_from_dense`(graph, null_value=0, nan_null=True, infinity_null=True, copy=True)

  Construct a masked array graph representation from a dense matrix.

  New in version 0.11.0.

  Parameters: | graph : array_like Input graph. Shape should be (n_nodes, n_nodes). null_value : float or None (optional) Value that denotes non-edges in the graph. Default is zero. infinity_null : bool If True (default), then infinite entries (both positive and negative) are treated as null edges. nan_null : bool If True (default), then NaN entries are treated as non-edges
  Returns: | csgraph : MaskedArray masked array representation of graph
