scipy.sparse.csc_matrix.has_canonical_format

property csc_matrix.has_canonical_format

Whether the array/matrix has sorted indices and no duplicates

Returns

• True: if the above applies

• False: otherwise

has_canonical_format implies has_sorted_indices, so if the latter flag is False, so will the former be; if the former is found True, the latter flag is also set.
