Expand description

Applies a binary operation to matching non-zero elements of two sparse matrices. When e.g. only the lhs has a non-zero at a given location, 0 is inferred for the non-zero value of the other matrix. Both matrices should have the same storage.

Thus the behaviour is correct iff binop(N::zero(), N::zero()) == N::zero()
