If you want to introduce a permanent loop opening at a signal as well, select one of the

following open-loop analysis point types:

• Open-Loop Input


• Open-Loop Output


• Loop Transfer


• Loop Break

When you define a signal as an open-loop point, analysis functions such as

getIOTransfer always enforce a loop break at that signal during linearization. All open-

loop analysis point types are equivalent within an slLinearizer interface. For more

information on how the software treats loop openings during linearization, see “How the

Software Treats Loop Openings” on page 2-44.

When you create an slLinearizer interface for a model, any analysis points defined in

the model are automatically added to the interface. If you defined an analysis point using:

• A closed-loop type, the signal is added as an analysis point only.


• An open-loop type, the signal is added as both an analysis point and a permanent
  opening.

Mark Analysis Points Programmatically

To mark analysis points programmatically, use the addPoint command. For example,

consider the scdcascade model.

open_system('scdcascade')
