function sys = mtt2sys (Name,par)

  ## usage:  sys = mtt2sys (Name[,par])
  ##
  ## Creates a sys structure for the Octave Control Systems Toolbox
  ## from an MTT system with name "Name"
  ## Optional second argument is system parameter list
  ## Assumes that Name_sm.m, Name_struc.m and Name_numpar.m exist
