Remove element from sparse matrix

Hey, I have a question. I have a sparse matrix:

W = [6 7 9 5 10];
S = [1 1 2 3 4];
D = [2 3 4 4 1];
DG = sparse(S,D,W);

After some testing, it turns out I have to remove (1,3) 7 (I have only the digits from S - 1 and D - 3 though, and not from W - 7). How do I remove that row directly from the sparse matrix without using:

W(i) = [];
S(i) = [];
D(i) = [];

Please help! :D

DG(S(i), D(i)) = 0;

Depending on what you are doing it might also make sense to remove from S and D and W, but doing so would not in itself affect DG.

It works, thanks a lot! :D
