1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution (a) I find the steady state values (s=0) Code (Text): syms s k11 = -6; k12 = 3; k21 = 12; k22 = 35; G = [k11 k12; k21 k22]; Ghat = [k22/(k11*k22-k12*k21) -k12/(k11*k22-k12*k21); -k21/(k11*k22-k12*k21) k11/(k11*k22-k12*k21)]; Lam = G*Ghat Lam Lam = 1 0 0 1 So I know that input 1 goes with output 1, and input 2 goes with output 2. (b) I am not sure how I should do this, but I look at steady state values Code (Text): G = -6 3 12 35 But I don't really know how steady state infusion rates can be zero, yet you can increase Cardiac output by infusion? I don't understand how to solve this question.
