A(q*e1) = 0 mod q is a trivial solution with l_2 and l_inf. In the centered representation we're using signed modulus range [-(q-1)/2,(q-1)/2] as clarified in malb#111

Thanks. Maybe we should distinguish between ISIS and SIS here? |

A(q*e1) = 0 mod q is a trivial solution for when the input bound is >= q for both l_2 and l_inf norms. In the centered representation we're using signed modulus range [-(q-1)/2,(q-1)/2] as clarified in #111
