scipy.sparse.csgraph.csgraph_from_dense¶

scipy.sparse.csgraph.csgraph_from_dense(graph, null_value=0, nan_null=True, infinity_null=True)¶

Construct a CSR-format sparse graph from a dense matrix.

New in version 0.11.0.

Parameters:

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 : csr_matrix Compressed sparse representation of graph,

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 : csr_matrix

Compressed sparse representation of graph,
