scipy.sparse.csgraph.csgraph_masked_from_dense

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
