The code computes the optimal reduced order state space model for a given system represented in state space.
The method used to find the reduced order model is based on the paper by Chidambara.

would result in ss(A_1,B_1,C_1,D_1) being the optimal reduced order model for the state space ss(A,B,C,D). The optimal order is given in the output variable r_opt.
