mpt_sys

 MPT_SYS Converts an object to sysStruct structure

 ---------------------------------------------------------------------------
 DESCRIPTION
 ---------------------------------------------------------------------------
 Converts a given object to MPT's system structure. The following objects can
 be converted:
   HYS  - HYSDEL source code
   SS   - State-Space objects of Control Toolbox
   TF   - Transfer-function objects of Control Toolbox
   IDSS - State-Space objects of Identification Toolbox
   MPC  - objects of MPC Toolbox

 ---------------------------------------------------------------------------
 USAGE
 ---------------------------------------------------------------------------
 General usage:
   sysStruct = mpt_sys(object, Ts, flag1, flag2)

 To convert a HYSDEL model, call:
   sysStruct = mpt_sys('hysdelsource')  - provide name of HYSDEL file

 To convert a HYSDEL model without creating an equivalent PWA representation:
   sysStruct = mpt_sys('hysdelsource', 'nopwa')

 To convert a HYSDEL model without generating a simulator:
   sysStruct = mpt_sys('hysdelsource', 'nosimulator')

 Note: The 'nopwa' and 'nosimulator' flag can be also used together, e.g.
   sysStruct = mpt_sys('hysdelsource', 'nopwa', 'nosimulator')


 To convert from an object, call:
   sysStruct = mpt_sys(obj)
 e.g.
   di_ss = ss([1 1; 0 1], [1; 0.5], [1 0], 0);
   sysStruct = mpt_sys(di_ss, 2)   - discretize the system with sampling time 2
                                     secs
 
 To convert a non-linear system given a function handle 
 (see "help mpt_nonlinfcn" for details):

   sysStruct = mpt_sys(@handle_to_function)

 INPUT
 ---------------------------------------------------------------------------
 obj          - Input object
 Ts           - Sampling time
 flag1        - 'nopwa' if no MLD-to-PWA translation should be done
 flag2        - 'nosimulator' if no HYSDEL simulator should be generated

 OUTPUT
