“…2) consists in taking the derivatives C (i) ω,N (t, τ ), i ∈ {1, 2, 3, 4, 5} of the BC-NK (13), then in identifying the terms C ω,N |i,j , with j ∈ {1, 2, 3, 4, 5, 6} (see (14) and (15)), and finally in computing C ω,N |i,j (t, t) to form the E i (t) matrices (see (18)) needed for the implementation of the auxiliary signal generation system G u,y→ze (see (17)). …”
