-// The product of a diagonal matrix with a sparse matrix can be easily
-// implemented using expression template.
-// We have two consider very different cases:
-// 1 - diag * row-major sparse
-//     => each inner vector <=> scalar * sparse vector product
-//     => so we can reuse CwiseUnaryOp::InnerIterator
-// 2 - diag * col-major sparse
-//     => each inner vector <=> densevector * sparse vector cwise product
-//     => again, we can reuse specialization of CwiseBinaryOp::InnerIterator
-//        for that particular case
-// The two other cases are symmetric.
