GSS:

-------------------------------------------------------------------------------
   Compute the frequency response of the system
   .
   x = ax + bu
   y = cx + du

   or

   G(s) = c*inv(sI-a)*b + d

   y(s) = G(s)*u(s)

   For example, for 3 outputs and 2 inputs g is of the form

                   w(1)               w(2)       ...
   output 1 [ input 1 input 2 | input 1 input 2 |... ]
   output 2 [ input 1 input 2 | input 1 input 2 |... ]
   output 3 [ input 1 input 2 | input 1 input 2 |... ]

   Form:
   [g,nu,w] = GSS(a,b,c,d,iu,iy,w)
