“…This includes the special case where the sample times are t i = iν for all i ∈ Z 0 , in which case we can take η = ν and S = {(r, r + ν) ∈ R 2 : r ∈ [0, p 0 ]}. Although fundamental solutions for the known matrices M and M ± δ are used in the formula for the control and in (9), they can be computed from solving matrix valued differential equations, e.g., using the method from [10]. In fact, as noted in [10], we can compute Φ A (t, s) for any piecewise continuous locally bounded square matrix valued function A by writing Φ A (t, s) = α A (t)β A (s) where α A and β A are the unique solutions of the matrix differential equations…”
