Problem 3. (25 pts) Let A = [ 1 1 0 − 1 ] . {"version":"1.1","math":"[ A=begin{bmatrix}1 & 1\0 & -1 end{bmatrix}. ]"} (5 pts) Find the eigenvectors of A . {"version":"1.1","math":"(A.)"} (10 pts) Find all the modes of the linear time-invariant system (LTI) continuous-time (CT) system, x ˙ = A x {"version":"1.1","math":"(dot{x}=Ax )"}, and write the solution from initial state x ( 0 ) = [ 1 2 ] ⊤ {"version":"1.1","math":"(x(0)=begin{bmatrix}1 & 2 end{bmatrix}^top )"}as a linear combination of modes. (10 pts) Find all the modes of the linear time-invariant (LTI) discrete-time (DT) system, x [ k + 1 ] = A x [ k ] {"version":"1.1","math":"(x[k+1]=Ax[k] )"}, and write the solution from initial state {"version":"1.1","math":""} x [ 0 ] = [ 3 2 ] ⊤ {"version":"1.1","math":"( x[0]=begin{bmatrix}3 & 2 end{bmatrix}^top )"}as a linear combination of modes.
