            Bug ID: 13831
           Summary: ss2ss does not transform initial state
           Product: Scilab software
           Version: 5.5.2 final version
          Hardware: PC
                OS: All OS
            Status: NEW
          Severity: Minor
          Priority: P5
         Component: CACSD
          Assignee: bugzilla.admin at scilab.org
          Reporter: Gerwald.Lichtenberg at haw-hamburg.de

BUG DESCRIPTION:
----------------

ss2ss always gives a zero initial state vector of the transformed system. 


ERROR LOG:
----------

no runtime errors, but code in function ss2ss missing !


HOW TO REPRODUCE THE BUG:
-------------------------

easiest example e.g. transform SISO first order system by:

ss2ss(syslin('c',-1,1,1,0,1),2)

transformed initial state given by ans(6) is 0, but should be 0.5


OTHER INFORMATION:
------------------

ss2ss should take into account that the initial state is transformed too and x0_new = T*x0_old
