Consider the system ẋ = Ax + bu, y = cx, where A, b and c are as follows:
A = [-42 148 82; -14 51 28; 6 -24 -13], b = [-2; 2; 4], c = [2 1 4].
(a) Compute the right and left e-vectors of A as well as the e-values (use Matlab).
(b) Compute a basis for the controllable subspace, Q, in terms of the right e-vectors.
(c) Compute a basis for the unobservable subspace, U, in terms of the right e-vectors.
(d) Is the system BIBO stable?
(e) Find the controllable and observable part of the system.
