NNZ

(2) Generally, the number of nonzero elements (nnz) in sparse matrix is way smaller than [n.sup.2].

Carry-Fresh[R] packaging from NNZ Industrial Packaging have been awarded a Worldstar by the World Packaging Organization.

One should be aware of the fact that duplicates occupy about 20% of all nonzero entries (NNZ) of sparse global matrices stored in the COO format so the number of atomic operation is large.

Auckland, Sep 16(ANI): The second report from an independent security firm engaged by Netball New Zealand (NNZ) and Hockey New Zealand (HNZ) has raised no fresh concerns ahead of next month's Delhi Commonwealth Games.

It is of size n = 3200 with a symmetric non-zero pattern and nnz = 18880 nonzero entries.
