scipy.sparse.csr_array.has_canonical_format#
- property csr_array.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.
