In the discussion preceding Algorithm 8.3, an example for m = 4 was explained. Define vectors c, d, e, f , and y as c = (c0, ... , c7) t , d = (d0, ... , d7) t , e = (e0, ... , e7) t , f = (f0, ... , f7) t , y = (y0, ... , y7) t . Find matrices A, B, C, and D so that c = Ad, d = Be, e = C f, and f = Dy.
