csgraph_to_masked#
- scipy.sparse.csgraph.csgraph_to_masked(csgraph)#
- Convert a sparse graph representation to a masked array representation - Added in version 0.11.0. - Parameters:
- csgraphcsr_array, csc_array, or lil_array
- Sparse representation of a graph. 
 
- Returns:
- graphMaskedArray
- The masked dense representation of the sparse graph. 
 
 - Examples - >>> from scipy.sparse import csr_array >>> from scipy.sparse.csgraph import csgraph_to_masked - >>> graph = csr_array( [ ... [0, 1, 2, 0], ... [0, 0, 0, 1], ... [0, 0, 0, 3], ... [0, 0, 0, 0] ... ]) >>> graph <Compressed Sparse Row sparse array of dtype 'int64' with 4 stored elements and shape (4, 4)> - >>> csgraph_to_masked(graph) masked_array( data=[[ --, 1.0, 2.0, --], [ --, --, --, 1.0], [ --, --, --, 3.0], [ --, --, --, --]], mask=[[ True, False, False, True], [ True, True, True, False], [ True, True, True, False], [ True, True, True, True]], fill_value=1e+20)
