Discrete-time affine systems. Given A E Rnxn and b E Rn, consider the discrete-time affine system x(k+ 1) = Ax(k) + b. Assume A is convergent and show that (iii) limk x(k) = (In A)-b for all initial conditions x(0) R. - Hint: Define a new sequence y(k), k = Zo, by y(k) = x(k) - x* for an appropriate x*.
