Set the degree to 2048. First, I transform two polynomials a(x) and b(x) by means of CT butterfly; Then, I need to multiply them in a element-wise style. Note that this is essential to modulo q after element-wise mul. Last, GS butterfly will transform into final result. But I failed. So, Do you have any feasible suggestions? Thank you so much.
