1function e = nnz (G) 2%NNZ the number of nonzeros in a matrix. 3% e = nnz (G) is the number of nonzeros in a GraphBLAS matrix G. A 4% GraphBLAS matrix G may have explicit zero entries, but these are 5% excluded from the count e. Thus, nnz (G) <= GrB.entries (G). 6% 7% See also GrB.entries, GrB.prune, GrB/nonzeros, GrB/size, GrB/numel. 8 9% SuiteSparse:GraphBLAS, Timothy A.
