Function Synopsis

ident(sessname,pathname)

Help text

IDENT  Starts the Graphical User Interface for the System Identification Toolbox.

   ident   or  ident(SESSION,PATH)
   
   IDENT by itself opens the main interface window.
   SESSION is a SITB session file (typically with extension .sid)
   PATH is the search path for this file. (Not necessary if on the
   MATHLABPATH.) When SESSION is specified, the interface opens
   with this session.
   
   When the interface is active, ident(SESSION,PATH) will open the
   session SESSION.
