% Compute the Algebraic Ricatti Equation (ARE) solutions
% for the optimal controller and for the Kalman filter.
% INPUTS
%   Sw = process noise covariance matrix.
%   Sv = measurement noise covariance matrix.
% OUTPUTS
%   pi1 = optimal control ARE solution for the first local T-S model.
%   pi2 = optimal control ARE solution for the second local T-S model.
%   P1 = Kalman filter ARE solution for the first local T-S model.
%   P2 = Kalman filter ARE solution for the second local T-S model.
