Question:

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.
