mat-vec-prod-exp

Matrix vector product experiments

Instructions:

• Just run cargo test -- --nocapture and the number of constraints will be printed
• Can comment & uncomment lib.rs lines 71 & 72 to test the different approaches:

  let Az = mat_vec_mul_sparse_gadget(A, z);
  // let Az = handcrafted_A_by_z(cs, z)?;
