Strongly recommended



MATLAB Versions





For some items it is not possible to define a single approach that is applicable to all organizations’ internal processes. However, it is important that within a given organization, a single consistent approach is followed. An organization applying the guidelines must enforce one of the following alternatives.

Apply one of the following practices:

  • The name of an Inport or Outport block is not hidden. (Format > Hide Name is not allowed.)

  • The name of an Inport or Outport block must be hidden. (Format > Hide Name is used.)

    Exception: The names cannot be hidden inside library subsystem blocks.

Correct: Use of signal label
