Re: [julia-users] Iterating over non-zero entries of a sparse matrix
nzrange will work but is not as convenient.
Re: [julia-users] Iterating over non-zero entries of a sparse matrix
So `findnz` converts the matrix to a tuple of arrays (triplet), and it creates a copy of all data. So it is not quite what I was looking for. An iterator would be better.

missed that - thank you.

[julia-users] Iterating over non-zero entries of a sparse matrix
Is there as iterator implemented that allows me to iterate over all non-zero entries of a sparse matrix or vector? E.g. for (i, j, z) in nonzeros(A) (I realise that nonzeros does something else!)
